Description

  The present invention relates to a blow-out port device which is disposed at a ceiling portion in a space to be air-conditioned and which blows conditioned air from the blow-out opening to the air-conditioned space.

  In air conditioning in which conditioned air is sent into the indoor space from the outlet device, various methods are adopted according to the target indoor space and the surrounding environment. For example, air conditioning of guest rooms and the like in a hotel is lowered to a predetermined location (for example, the vicinity of the guest room entrance) of the ceiling in the guest room relative to other indoor parts of the ceiling due to space limitations and cost constraints. The air conditioner is arranged from the outlet which is provided sideways with respect to the indoor space of the outlet device, which is provided so as to accommodate the outlet device in the lower ceiling, and which is disposed on the side of the lower ceiling. In many cases, the air is blown out to the indoor space as it is and the conditioned air is diffused to the indoor space.

And, in the air outlet device for each guest room of such a hotel, a fan coil unit using a heat medium common to each room is combined to generate temperature-controlled conditioned air, or air conditioning of the machine room The conditioned air can be blown out from the outlet device by supplying the conditioned air that has been centrally processed by the machine to each of the outlet devices through the duct.
As an example of such a conventional blower outlet apparatus, there exist some which are described in Unexamined-Japanese-Patent No. 7-145983 and Unexamined-Japanese-Patent No. 7-42472.

JP 7-145983 A Japanese Utility Model Publication 7-42472

  The conventional air outlet apparatus shown in each of the patent documents blows out the conditioned air sideways in the vicinity of the ceiling in both cases of cooling and heating. For this reason, when heating, there is a problem that it is lighter than room air, and mixing with room air does not occur easily with warm air which tends to remain near the ceiling even after blowout.

  On the other hand, even in indoor spaces such as hotel rooms where conventional air outlet devices are applied, as in the case of offices and general household rooms, in recent years, LEDs with little heat generation are adopted for indoor lighting, etc. In the room, the amount of heat released from other than the air conditioner is decreasing, and the heating load of the indoor space in the heating period tends to increase accordingly.

  For this reason, in the application to the indoor space of the conventional blower outlet apparatus, for example, when the room is large and the indoor space is large or the area of the glass window is large and the amount of heat dissipated from there increases, heating is There is a problem that it is easy for the heating capacity to be insufficient for the load, and the problem of mixing of the warm air and the indoor air makes it difficult to warm up the room even if the heating is performed.

  In particular, considering the application to hotel rooms, hotel rooms are generally used at night, such as lodging, and heating problems such as warmth are required for the room's air conditioning function It may lead to dissatisfaction in the hotel use of the guest as it is because it can not be fully demonstrated at the same time. Since such dissatisfaction can also cause customers to lose their next visit, there is a strong demand for improvement in the above-mentioned heating problems.

  The present invention has been made to solve the above problems, and the guide vanes make the guiding direction of the air flow of the conditioned air variable between horizontal and diagonally downward, and open and close the shutter portion inside the outlet. The air conditioning effect can be enhanced by efficiently advancing the mixing of the conditioned air and the indoor air by making it possible to adjust the blowing speed and blowing the conditioned air flow which is increased in the flow speed obliquely downward from the blowout port if necessary. It is an object of the present invention to provide an enhanced outlet apparatus, a control method of the outlet, and an air conditioning system to which the control method is applied.

  The blower outlet device according to the present invention is disposed in the ceiling of the air conditioning target space or in the vicinity of the ceiling, and in the blower outlet device for blowing the conditioning air into the air conditioning target space, the laterally internal flow passage through which the conditioning air can pass. It is formed as a substantially box-like body surrounding, has a plurality of openings leading to the internal passage, is provided in the vicinity of the ceiling of the air conditioning target space, and one of the openings leading to the internal flow passage is conditioned air. An outlet main body which is supplied and blows conditioned air into the air conditioning target space from the other opening, and a shutter part provided inside the outlet main body and capable of opening and closing a lower predetermined range of the internal flow path; In the vicinity of the other opening in the inside of the blowout body, a plurality of guide vanes arranged so as to be tiltable around a tilting central axis crossing the internal flow path, and in the inside of the blowout body Upper edge Continuously for a predetermined length toward the opening side of the other, it is disposed in and across the internal passage, in which and a substantially plate-like partition portion dividing the predetermined range of internal channel up and down.

  As described above, according to the present invention, a shutter portion for opening and closing the lower portion of the internal flow path of the outlet body is provided in the inside of the outlet body provided on the ceiling or in the vicinity thereof. The guide vanes of the above are arranged to be tiltable, and a partition part is provided to divide the internal flow path of the outlet body up and down at the other opening position of the upper end of the shutter part, and the shutter part is closed. While increasing the velocity of the air flow by decreasing, a region of relatively low pressure is produced on the downstream side of the air flow direction of the shutter by the action of the partition portion, and a state where the air blowing direction is easily shifted downward can be obtained. Therefore, the air flow of the conditioned air, which has increased the flow velocity, is blown out diagonally downward without any difficulty by closing the shutter portion inside the blowout body together with the adjustment of inclining each guide blade downward. For example, in the case of heating, if the air is blown downward obliquely, the warm air is strongly mixed with the surrounding room air while advancing obliquely downward in the indoor space, and is diffused into the room. Thus, it is possible to prevent the rising of the blown-out warm air and the progress of the warm air along the ceiling, and to efficiently promote the mixing of the warm air and the indoor air to enhance the heating effect of the room.

  In the air outlet apparatus according to the present invention, a resistor for partially closing the flow path portion may be provided in the flow path portion above the shutter portion in the inner flow path of the air outlet body, as necessary. The ratio of the size of the open portion not blocked by the resistor in the upper flow path portion to the entire upper flow path portion is the size of the open portion in the shutter portion when the shutter portion is open to the entire shutter portion It matches the ratio.

  As described above, according to the present invention, when the resistor is provided in the flow passage portion on the upper side of the shutter portion in the inner flow passage of the outlet body, and the shutter portion is opened, the upper flow in the inner flow passage The opening ratio of the passage portion, ie, the ratio of the size of the open portion not blocked by the resistor in the upper passage portion to the entire upper passage portion, is By setting the closed state of the resistor so as to correspond to the ratio of the size to the entire shutter unit, the shutter unit can not be made to have an open area ratio of 100% even in the open state. In the open state of the shutter unit, the air flow of the conditioned air is performed by the open portion of the shutter unit and the upper flow passage portion in the internal flow passage, with the upper flow passage portion as the same opening ratio as the resistor. It is possible to uniformly apply passage resistance and distribute the air flow evenly in the upper and lower portions of the internal flow passage, and when the shutter portion is opened to blow out from the entire other opening of the outlet body, the guide vanes Air can be blown out uniformly from the entire opening in a desired direction guided by the air conditioner, and the air flow of conditioned air can be appropriately advanced to the indoor space to advance air conditioning.

  In the air outlet apparatus according to the present invention, the guide vanes are formed substantially in the shape of a thin plate whose surface is curved, if necessary, and the vanes are separated from the tilting central axis of the vanes in the vane cross-sectional shape. The shape at at least one end is curved downward to guide the air flow along the guide vanes downward in a state where the guide vanes are inclined and turned obliquely.

  As described above, according to the present invention, when the air flow is blown obliquely downward with the guide blade end portion having a predetermined curved shape and the guide blade is directed obliquely, the air flow is directed obliquely along the curved portion of the guide blade end portion. When the air flow is directed obliquely downward at the time of heating, the warm air that easily rises can be smoothly directed downward of the indoor space by the guidance of the guide vanes and efficiently mixed with the indoor air. It can be diffused, and the efficiency of heating can be increased.

  In the air outlet apparatus according to the present invention, the shutter unit may be configured to have a flow passage cross-sectional area of a lower predetermined range portion in the inner flow passage of the air outlet main body, as required. It is disposed to be larger than the flow passage cross sectional area of the upper flow passage portion.

  As described above, according to the present invention, the flow passage cross-sectional area of the lower portion with the shutter portion in the inner flow passage is made larger than the flow passage cross-sectional area of the upper flow passage portion, and the shutter portion is opened and closed. By giving a great influence to the flow path, the upper flow path portion maintaining the open state is narrowed when the shutter portion is closed to increase the velocity of the air flow, and the distance of the air flow in the indoor space is increased. As the area of low pressure generated on the downstream side of the air flow direction of the shutter becomes larger, the influence on the blowout air flow of this area is also greater. The air flow can be appropriately directed downward without any difficulty, and the air flow with increased speed can be blown out obliquely downward surely, and the indoor space can be advanced as it is. More Unagaseru mixing of the room air and.

  In the air outlet device according to the present invention, the predetermined range portion near the other opening in the partition may be inclined with respect to the other portion of the partition, as needed. The inclination angle is set to direct the tip of the inclined portion toward the lower end of the other opening.

  As described above, according to the present invention, the air flow having traveled along the inner flow path along the partition is inclined as it is by tilting the end of the partition and directing the tip to the lower end side of the other opening. It reaches the lower end of the other opening of the blowout body along the portion, passes through the lower end of the opening, and proceeds to the indoor space, and the air flow reaching the lower end of the opening from the inclined portion of the partition is the partition of the internal flow passage As a state in which the lower side portion is separated from the indoor space, it is possible to prevent the room air from moving toward the area where the pressure is lower on the downstream side of the air flow traveling direction than the shutter portion. It is possible to reliably prevent the occurrence of dew condensation by bringing warm room air into contact with the inner peripheral surface of the unit, the shutter unit, and the outlet body.

  The control method of blowing out of the outlet apparatus according to the present invention is the control of the blowing state in the outlet apparatus which is disposed on the ceiling or the ceiling of the indoor space to be air-conditioned and blows conditioned air into the indoor space. In the method, the outlet device is formed as a substantially box-like body surrounding an internal flow passage through which the conditioned air can pass, and an opening that blows the conditioned air into the inner passage faces the air conditioning target space. And an outlet main body disposed inside the outlet main body to change the degree of opening of at least a part of the internal flow passage and adjust the air flow speed of the conditioned air blown out from the opening And a blowout direction of the conditioned air blown out from the opening toward the living area in the indoor space. Small amount At least a plurality of control blades for adjusting and controlling the plurality of guide vanes that can be switched to a plurality of ways including at least one of the plurality of ways and the opening degree of the shutter portion and the inclination angle of the guide vanes When the means acquires the confirmation information that the user enters the indoor space after a predetermined time, the advance air conditioning instruction information to the indoor space is sent to the control unit, and the control unit receives the advance air conditioning instruction information. The shutter unit is closed, and the guide vanes are adjusted to an inclination angle for guiding the conditioned air in the downward blowing direction, so that the conditioned air blown out from the opening flows into the living area in the indoor space And the control unit causes the shutter unit to be in the open state and the guide vanes to be in the state of directly arriving at the same time as or before the user enters the indoor space. By adjusting the inclination angle to direct the conditioned air in the other blowing direction other than the close blowing direction, the air flow of the conditioned air blown out from the opening is switched to a state where it does not directly reach the living area in the indoor space is there.

  As described above, according to the present invention, when it is determined that the user enters the indoor space after a predetermined time, the shutter unit is closed based on the control by the control unit, and the guide vanes The conditioned air, which is adapted to guide the conditioned air in the downward blowing direction, and whose air flow speed is increased from the opening of the outlet body, is guided by the guide vanes and blown downward to the indoor space, resulting in a large air flow By reaching the living area below the indoor space by the speed, the diffusion of the conditioned air accompanying the mixing of the conditioned air and the indoor air in the living area proceeds rapidly, and the temperature of the indoor air is efficiently raised in a short time or The temperature is lowered to shift to the set temperature of the air conditioning, and the indoor space when the user enters the room can be made more comfortable.

  In addition, when the user enters the indoor space, the control unit opens the shutter unit and adjusts the tilt of the guide vanes so that the air flow of the conditioned air blown out from the opening is directly in the living area By not reaching the state, the air flow of the conditioned air blown out into the indoor space does not become a draft for the user and does not give a sense of discomfort when the user is in the indoor space. The comfortable state of the indoor space by the harmony will be surely obtained.

  In the blowout control method of the blowout apparatus according to the present invention, the user may enter the indoor space immediately before entering the indoor space, which is estimated in advance by the external control unit or the control unit based on the determination information as needed. Upon reaching or obtaining information indicating the fact of the user's entry into the indoor space, the control unit causes the conditioned air flow to reach the living area from the state where the conditioned air flow directly reaches the living area. Is to switch to a state where it does not reach directly.

  As described above, according to the present invention, while the conditioned air is in the state of directly reaching the living area in the indoor space as the air flow, the control unit has reached the estimated time immediately before the user enters the indoor space. When the control unit acquires information that indicates the fact that the user has entered the indoor space, the control unit switches the outlet device to a state in which the air flow of the conditioned air does not reach the living area directly, and the room condition By ensuring that the air flow of the conditioned air does not become a draft for the user of the user, the control unit automatically recognizes the timing of entering the room correctly, and the air flow of the conditioned air until immediately before the user enters the indoor space Is able to maximize the efficiency of air conditioning that reaches the living space below the indoor space, ensure that the room temperature at the time of the user's entry approaches the air conditioning set temperature, and the user's sense of comfort in the room Direction Provoking.

First Embodiment of the Present Invention
Hereinafter, an outlet apparatus according to a first embodiment of the present invention will be described based on FIGS. 1 to 11. In the present embodiment, an example of an air outlet apparatus provided in a falling ceiling portion of an indoor space such as a guest room of a hotel will be described.

  In each of the drawings, the outlet device 1 according to the present embodiment is provided in the inside of the outlet body 10, and the outlet body 10 formed as a substantially cylindrical body surrounding the internal flow passage having a rectangular opening cross section. A shutter portion 20 capable of opening and closing a lower predetermined range of the internal flow passage, a plurality of guide vanes 30 disposed in a tiltable manner in the vicinity of the other opening in the inside of the outlet body 10; It is configured to include a partition portion 40 disposed inside to divide the internal flow path up and down, and a resistor 50 provided in a flow path portion above the shutter portion 20 in the internal flow path of the outlet body 10.

  The air outlet main body 10 is formed as a substantially cylindrical body made of a high strength material such as metal surrounding a flow passage having a rectangular opening cross section through which conditioned air can pass, and is a ceiling of an indoor space to be air-conditioned. The openings at both ends of the internal flow path are provided to be horizontal.

  The outlet main body 10 is disposed inside the lowered ceiling portion 65 which is one step lower in the ceiling 60 so that the rectangular opening cross section becomes horizontally long (see FIG. 1). The conditioned air is supplied to the one opening 11 to be connected, and the conditioned air is blown out to the indoor space 70 from the other opening 12 disposed in the exposed state on the side surface portion of the lower ceiling portion 65.

At the end portion on the indoor space side of the outlet body 10, a frame portion 13 projecting from the end portion around the opening 12 is formed.
The frame portion 13 has a configuration in which a portion protruding outward by a predetermined width from the end portion on the side of the outlet body 10 is continuously formed in a circumferential direction to have a substantially bowl shape. Then, the frame portion 13 is in contact with the opening edge portion of the side surface of the lower ceiling portion of the ceiling 60, thereby preventing the leakage of the conditioned air from the gap between the outlet body 10 and the lower ceiling portion 65. It is.

  Besides, the shutter portion 20 is provided near the one opening 11 and the plurality of guide vanes 30 are provided in the vicinity of the other opening 12 inside the blowout body 10, and the shutter portion 20 and the guide vane 30 are The partition part 40 will be provided between.

  The shutter portion 20 moves the movable portion 22 with respect to the fixed portion 21 so that the openings provided in each overlap and the open state where the harmonized air can pass, and the openings deviate and do not overlap each other. A known slide shutter capable of switching to a closed state in which air is not allowed to pass, provided as a configuration crossing the lower part of the internal flow passage in the blowout main body 10, capable of opening and closing a lower predetermined range of the internal flow passage It is

  The shutter unit 20 has a drive unit 23 controlled by a predetermined control unit (not shown), and operates by driving the drive unit 23 controlled by the control unit based on the operation of the user. It is the structure which performs opening-and-closing switching.

  Specifically, in response to a control command based on the user's operation, the drive unit 23 which is a linear motor moves the projecting piece 24 coupled to the drive unit 23, and the shutter unit 20 to which the projection piece 24 is attached. The movable portion 22 is slidingly moved relative to the fixed portion 21 to switch between an open state in which the openings overlap each other to form an open portion 25 through which the conditioned air passes and a closed state in which the openings are mutually offset and do not overlap. It is a mechanism.

In addition, the flow passage cross-sectional area of the lower predetermined range portion in the inner flow passage of the outlet body 10 where the shutter portion 20 exists is made larger than the flow passage cross-sectional area of the flow passage portion above the shutter portion 20. The state of the internal flow passage of the blowout body 10 largely changes when the shutter unit 20 is opened and closed.
In addition, the shutter portion 20 is configured to be installed obliquely at an angle with respect to the inner peripheral surface of the outlet body 10 in order to secure a large effective opening area at the time of opening.

The guide vanes 30 are arranged in the vicinity of the other opening 12 in the inside of the blowout main body 10 so as to be tiltable around a tilting central axis crossing the internal flow passage, and a plurality of guide vanes 30 are vertically disposed at predetermined intervals.
The guide vanes 30 are formed in a substantially thin plate shape whose surface is curved, and have a point-symmetrical cross-sectional shape centered on the tilting central axis, the thickness of which decreases with distance from the tilting central axis.

  Further, the guide vanes 30 have a shape at an end away from the tilting central axis among the vane cross-sectional shapes, in a state where the guide vanes 30 are inclined and turned obliquely, the end near the other opening 12 In order to guide the air flow along the guide vanes 30 downward at the angle .beta.

  A drive unit 31 controlled by a predetermined control unit (not shown) is disposed in the blowout body 10 for tilting the guide vanes 30. The drive unit 31 applies a driving force to the guide vanes 30 under the control of the control unit based on the operation of the user to tilt the guide vanes 30 uniformly.

  In detail, the connection plate 33 connected to the end of each guide vane 30 together with the drive unit 31 is vertically movably disposed in the blowout body 10, and the connection plate 33 is a drive unit that is a geared motor. The end of the arm 32 attached to the output shaft of 31 and tilting is connected.

  When the drive unit 31 tilts the arm 32 in response to a control command based on the user's operation, the connecting plate 33 connected to the arm 32 moves up or down, and along with the movement of the connecting plate 33. Each guide vane 30 whose end is connected to the connecting plate 33 tilts around the tilt center axis to change the direction. When the connecting plate 33 moves downward, the guide vanes 30 tilt so that the other end on the side of the opening 12 moves upward, and when the connecting plate 33 moves upward, the same end of the guide vanes 30 moves downward. Ascend. When the connecting plate 33 moves to the lowermost position in the movable range, the other end of the guide vane 30 on the opening 12 side is directed to the side, and the entire vane is in a horizontal state in which the entire vane is substantially horizontal. When the connecting plate 33 further moves upward from there, the guide vanes 30 are directed obliquely downward with the end of the other opening 12 facing downward, and the entire vanes are inclined.

  In this manner, when the drive unit 31 tilts the guide vanes 30 via the arm 32 and the connection plate 33 under the control of the control unit, the guide vanes 30 can be switched between the horizontal direction and the oblique direction.

  The partition portion 40 is formed of a substantially plate-like body, and is disposed continuously from the upper edge of the shutter portion 20 in the inside of the outlet body 10 to the other opening 12 side for a predetermined length and across the internal flow path. The internal flow path is divided up and down over a predetermined length.

  The partition 40 separates and isolates an area downstream of the shutter 20 in the flow direction in the internal flow path from the flow path above the shutter 20, so that the partition is closed when the shutter 20 is closed. The pressure in the region on the downstream side of the air flow direction of the shutter unit 20 divided from the upper flow passage portion by 40 can be reduced relative to the upper flow passage portion.

  The resistor 50 is formed of a plate-like body provided with a plurality of through holes 51, and is provided in a flow passage portion above the shutter portion 20 in the inner flow passage of the blowout main body 10 so as to cross it. The upper channel portion is partially closed. In this resistor 50, the opening ratio of the upper flow passage portion, that is, the size of the open portion consisting of the respective through holes 51 not covered by the resistor 50 in the upper flow passage portion with respect to the entire upper flow passage portion Each through hole 51 is drilled so that the ratio matches the aperture ratio of the shutter unit 20 when the shutter unit 20 is opened, that is, the ratio of the size of the open portion of the shutter unit 20 to the entire shutter unit 20. Ru.

Moreover, in order to ensure the effective opening area as large as possible, the resistor 50 is installed obliquely at an angle with respect to the inner peripheral surface of the blower outlet body 10, similarly to the shutter unit 20.
By providing the resistor 50, in the open state of the shutter unit 20, the aperture ratio of the shutter unit 20 and the resistor 50 becomes the same, and the conditioned air passes through the respective open portions of the shutter unit 20 and the resistor 50. The air flow is distributed throughout the internal flow path, and the air flow is prevented from being distributed to the side having a large opening ratio and a small passage resistance, and the blowout direction by each guide vane 30 at the other opening 12 side of the blowout body 10 You can make settings properly.

  Next, the conditioned air blowing state in the air outlet apparatus based on the above configuration will be described. As a premise, it is assumed that conditioned air is continuously supplied to the outlet device 1 through the duct 61.

  When the blowout state of the outlet device 1 is set by the operation of the user, if it is necessary to switch the open / close state of the shutter unit 20 from the previous state in response to the set blowout state, Based on this, the drive unit 23 of the shutter unit 20 operates to switch the open / close state of the shutter unit 20.

  Specifically, the drive unit 23 of the shutter unit 20 operates based on the control corresponding to the user's operation, linearly moves the projecting piece 24 coupled to the driving unit 23, and is integral with the projecting piece 24. By sliding the movable unit 22 of the shutter unit 20 relative to the fixed unit 21, the shutter unit 20 is switched to a predetermined open / close state different from the previous one, corresponding to the content of the new air conditioning to the indoor space.

  Further, when it is necessary to switch the direction of the guide vanes 30 also from the previous direction according to the set blowout state, the drive unit 31 operates to switch the direction of the guide vanes 30 based on control. It will be.

  Specifically, the drive unit 31 operates to tilt the arm 32 based on the control corresponding to the user's operation, and moves the connecting plate 33 connected to the arm 32 of the drive unit 31 up or down. By tilting the guide vanes 30 whose ends are connected to the connecting plate 33 about the tilting central axis, the guide vanes 30 correspond to the contents of the new air conditioning to the indoor space. Switch to a different predetermined orientation.

  According to the setting of the blowing state, in the state where the shutter unit 20 is in the open state and the guide vanes 30 are in the horizontal direction (see FIGS. 4 and 5), the conditioned air sent from the duct 61 is the outlet body 10 The air enters the air outlet body 10 from one opening 11 of the The conditioned air reaches the shutter portion 20 and the resistor 50 in the outlet body 10.

  The conditioned air passes through both the shutter portion 20 and the resistor 50 in the open state, and both the upper flow path portion and the lower flow path portion sandwiching the partition portion 40 in the inner flow path in the outlet body 10 To reach the guide vanes 30 located closer to the indoor space.

  The conditioned air reaching the guide vanes 30 travels between the guide vanes 30 arranged in the vertical direction and is guided by the respective guide vanes 30 turned sideways, the traveling direction is made horizontal, and the interior of the other opening 12 is substantially indoors. The air is blown into the space 70.

The state in which the shutter portion 20 is in the open state, the guide vanes 30 are in the horizontal direction, and the conditioned air is blown out horizontally from almost the entire area of the other opening 12 is mainly used for cooling. By blowing cold air horizontally from the outlet device provided in the ceiling portion 65, it is possible to allow the indoor space to reach a distant place without immediately lowering the cold air heavier than the room air.
Further, by not narrowing the flow path of the conditioned air and not increasing the blowing speed excessively, it is possible to prevent the air flow of the cold air from reaching the living area and becoming a draft without reducing the speed when the indoor space is narrow.

  Subsequently, according to another setting of the blowing state, a state in which the shutter portion 20 is in the closing state and the guide vanes 30 are in the horizontal direction will be described (see FIGS. 6 and 7). In this state, the conditioned air sent from the duct 61 passes through one opening 11 of the outlet body 10 and reaches the shutter portion 20 and the resistor 50, but the conditioned air can not pass through the shutter portion 20 in the closed state. , Passes through the resistor 50 only.

  For this reason, the conditioned air passes through the resistor 50 and passes through the upper flow path portion of the internal flow path in the outlet body 10 above the partition 40, and the cross-sectional area of the flow path through which the conditioned air passes is The passage speed of the conditioned air is increased by making the flow path narrower than when passing through the entire internal flow passage, and the conditioned air having the increased flow rate reaches the guide vanes 30.

  The conditioned air that has reached the guide vanes 30 travels horizontally with the direction of travel as it is by the laterally oriented guide vanes 30. At this time, the conditioned air passes through only the flow passage portion on the upper side of the partition portion 40 of the inner flow passage while increasing the flow velocity, but does not pass through the flow passage portion on the lower side of the partition portion 40 In the flow path portion on the lower side of the portion 40, the pressure is reduced relative to the flow path portion on the upper side, and a flow of conditioned air that is advancing is attracted to the region where the pressure is lowered, and as a result, the conditioned air is A slight downward velocity component is added to the air flow.

  However, the conditioned air is guided by the respective guide vanes 30 which are made to face sideways, and the traveling direction is not greatly changed, and the air flow only spreads slightly lower than the passage of the flow path portion above the partition portion 40 The conditioned air is blown into the indoor space 70 from the area from the top to the center of the other opening 12.

  A state in which the shutter portion 20 is closed and the guide vanes 30 are oriented horizontally and the conditioned air is blown out horizontally from a partial region of the other opening 12 is also mainly used at the time of cooling. By blowing cold air from the air outlet device provided in the falling ceiling portion 65 at an increased blowing speed and blowing it horizontally, the cold air that is heavier than the room air is made to fall along the ceiling to the far side of the indoor space Even when the indoor space is wide, cool air can be diffused to the entire indoor space to perform cooling efficiently, and a cooling effect can be reliably obtained.

  Further, according to still another setting of the blowing state, a state in which the shutter portion 20 is in the closing state and the guide vane 30 is in the oblique direction will be described (see FIGS. 8 and 9). In this state, the conditioned air sent from the duct 61 passes through one opening 11 of the outlet body 10 and reaches the shutter portion 20 and the resistor 50, but the conditioned air can not pass through the shutter portion 20 in the closed state. , Passes through the resistor 50 only.

  For this reason, the conditioned air passes through the resistor 50 and passes through the upper flow path portion of the internal flow path in the outlet body 10 above the partition 40, and the cross-sectional area of the flow path through which the conditioned air passes is The passage speed of the conditioned air is increased by making the flow path narrower than when passing through the entire internal flow passage, and the conditioned air having the increased flow rate reaches the guide vanes 30.

  The conditioned air that has reached the guide vanes 30 changes its traveling direction obliquely downward by the obliquely oriented guide vanes 30. In addition, at this time, the conditioned air passes through only the flow passage portion on the upper side of the partition portion 40 of the inner flow passage while increasing the flow velocity, but does not pass through the flow passage portion on the lower side of the partition portion 40. For this reason, in the flow path portion on the lower side of the partition portion 40, the pressure is relatively reduced with respect to the flow path portion on the upper side, and the advancing air flow of conditioned air is attracted to the region where the pressure is lowered. The downward flow of conditioned air will be promoted as

  Thus, the conditioned air proceeds obliquely downward from the flow passage portion on the upper side of the partition portion 40 of the inner flow passage, passes between the obliquely oriented guide vanes 30, and makes the traveling direction obliquely downward, The air is blown into the indoor space 70 from the region from the top to the center.

  The state in which the shutter portion 20 is closed and the guide vanes 30 are directed obliquely and the conditioned air is blown obliquely downward from a partial region of the other opening 12 is mainly used at the time of heating. The warm air is blown out obliquely downward after increasing the blowing speed from the air outlet device provided at the falling ceiling portion 65, so that the warm air lighter than the indoor air is not immediately raised and the remote space of the indoor space Even when the indoor space is wide, the warm air can be diffused to the entire indoor space to efficiently heat the room, and the heating effect can be reliably obtained.

  Furthermore, according to the other setting of the blowing state, the shutter part 20 is made into the open state, and the state in which the guide blade | wing 30 was made into the diagonal direction is demonstrated (refer FIG. 10, FIG. 11). In this state, the conditioned air sent from the duct 61 passes through one opening 11 of the outlet body 10 to reach the shutter portion 20 and the resistor 50, and passes through both the shutter portion 20 in the open state and the resistor 50. The guide vanes 30 located closer to the indoor space are reached through both the upper flow passage portion and the lower flow passage portion sandwiching the partition 40 of the inner flow passage in the blowout main body 10.

  The conditioned air that has reached the guide vanes 30 travels between the guide vanes 30 arranged vertically and is guided by each of the guide vanes 30 that is directed obliquely, and the advancing direction is directed obliquely downward, substantially the entire area of the other opening 12 And blow off into the indoor space 70.

A state in which the shutter portion 20 is in the open state and the guide vanes 30 are in the oblique direction and the conditioned air is blown obliquely downward from almost the entire area of the other opening 12 is also mainly used at the time of heating. By blowing warm air obliquely downward from an outlet device provided at the lower ceiling portion 65, warm air lighter than room air can be reached far into the indoor space without immediately rising, and efficient heating can be performed. .
Further, by not narrowing the flow path of the conditioned air and not increasing the blowing speed excessively, it is possible to prevent the air flow of the warm air from reaching the living area and becoming a draft without reducing the speed when the indoor space is narrow.

  Thus, in the outlet device according to the present embodiment, the outlet body is provided inside the outlet body 10 provided in the lowered ceiling portion 65 of the ceiling 60 so that the opening 12 on the indoor space side is oriented horizontally. While providing the shutter part 20 which opens and closes the lower part of the internal flow path of 10, a plurality of guide vanes 30 are tiltably disposed in the vicinity of the other opening 12 of the outlet body 10, and further the other opening of the shutter part 20 upper end A divider 40 is provided to divide the internal flow path of the outlet body 10 up and down at a position 12 and the shutter 20 is closed, thereby increasing the air flow speed by reducing the flow path cross-sectional area in the internal flow path An area with a relatively low pressure is generated on the downstream side of the air flow direction of the shutter 20 by the guiding action of the part 40, and the air flow from the other opening 12 is shifted downward. Since the state can be obtained, when the shutter portion 20 inside the outlet body 10 is closed together with the adjustment for inclining each guide vane 30 downward, the air flow of the conditioned air having the flow velocity increased can be blown obliquely downward without difficulty. In the case of heating, if this blowing downward is performed obliquely, warm air will be mixed strongly with the surrounding room air while advancing obliquely downward in the indoor space, and will be diffused into the room. Thus, it is possible to prevent the rising of the blown-out warm air and the progress of the warm air along the ceiling 60, and to efficiently promote the mixing of the warm air and the indoor air to enhance the heating effect of the room.

  In the blowout apparatus according to the embodiment, five guide vanes 30 are provided. However, the present invention is not limited to this, and it is based on conditions such as the volume and temperature of conditioned air blown out from the blowout. An appropriate number of guide vanes can be arranged to correspond to the size of the selected outlet device, in particular the size of the other opening 12.

  Further, in the blowout apparatus according to the embodiment, the slide unit 20 is configured to use a slide shutter for moving the movable unit 22 relative to the fixed unit 21. However, the present invention is not limited to this. A mechanism such as a shutter, which always has a predetermined mechanical part in the internal flow path regardless of opening and closing, and which serves as a resistor to the air flow, almost generates passage resistance in the open state allowing the air flow It is also possible to adopt a configuration that does not allow this, for example, that in which a closing portion such as a butterfly type damper tilts.

  Moreover, in the blower outlet apparatus which concerns on the said embodiment, although the one opening 11 and the other opening 12 which both lead to the horizontal internal flow path of the blower outlet main body 10 are made transversely, it is not restricted to this, One opening 11 on the supply side of the conditioned air can be set in another direction corresponding to the upstream device such as the installation condition and the duct for the supplied conditioned air.

Second Embodiment of the Present Invention
In the air outlet apparatus according to the first embodiment, the partition 40 provided in the air outlet body 10 is formed in a flat plate shape, but as shown in FIG. 12 as another embodiment. Alternatively, the predetermined range portion closer to the other opening 12 in the partition portion 40 may be formed as the inclined portion 41 as a shape inclined with respect to the other portion of the partition portion 40.

  The inclination angle of the inclined portion 41 of the partition portion 40 is set to be a predetermined angle to direct the tip end of the inclined portion 41 toward the lower end of the other opening 12. For example, it is preferable to set the angle formed by the inclined portion 41 to be about 7.5 ° with respect to a virtual horizontal plane corresponding to the other portion of the partition portion 40 extended toward the other opening 12 side. In this case, the air flow that has traveled the internal flow path along the partition 40 changes its traveling direction obliquely downward along the inclined portion 41 and reaches the lower end of the other opening 12 of the outlet body 10 It will advance to the indoor space 70 through the opening lower end.

  The air flow reaching the lower end of the opening from the partition inclined portion 41 separates the portion of the internal flow path of the outlet body 10 below the partition 40 from the indoor space. It is possible to prevent the area 20 from becoming a lower pressure downstream of the direction of air flow traveling from the portion 20, and in the case of cooling, on the inner circumferential surface of the partition 40, the shutter 20 and the outlet body 10 cooled by contact with the blowing air. Condensation can be reliably prevented from coming in contact with warm indoor air.

Third Embodiment of the Present Invention
The blower outlet apparatus which concerns on the 3rd Embodiment of this invention is demonstrated based on said FIG. 13 thru | or FIG. In the present embodiment, an example of a blow-out port device provided in a falling ceiling of a hotel room will be described.

  As in the first embodiment, the blowout apparatus 1 according to the present embodiment in each of the drawings includes the blowout body 10, the shutter unit 20, the guide vanes 30, the partition unit 40, and the resistor 50 as in the first embodiment. On the other hand, the difference is that the degree of opening of the shutter unit 20 can be further switched to two steps, and the inclination angle of the obliquely oriented state of the guide vanes 30 can be further switched to two steps. The room before the user enters the room, in addition to the switching adjustment of the shutter unit 20 and the guide vanes 30 to any of the three selectable states to correspond to the blown-out state set by the user In the case where air conditioning is performed in advance of the space, a blowout state corresponding to the air conditioning is obtained.

  In particular, the control unit 80 that controls switching between the shutter unit 20 and the guide vanes 30 is disposed for each indoor space (guest room) to be air-conditioned for the air outlet device, and corresponds to other indoor spaces. The system is communicably connected to the central control unit 90 as the external control means together with the control unit of the blowout device to form one system (see FIG. 13), and the preceding air conditioning to the indoor space before the user enters the room It receives control information such as whether or not to perform control related to the above, and a command of execution timing of advance air conditioning.

The central control unit 90 is connected to the control unit 80 of each air outlet apparatus 1 for each guest room of the hotel, and whether or not to permit each control unit 80 to perform control related to prior air conditioning to their indoor space It is connected with the hotel's room management system 100 that handles check-in and check-out information and reservation information at the hotel as well as determines control, sends control permission commands, and checks the facts of user check-in and check-out Based on control to acquire and transmit to the control unit 80 as information, and the fact of the user's check-in, that is, determined information that the user after this check-in enters the indoor space (guest room) after a predetermined time. Control information sent to the control unit 80, and various information such as check-in scheduled time based on user's reservation information, and control Performs control to send the control unit 80.
In addition, the blower outlet main body 10 in this embodiment, the partition part 40, and the resistor 50 are the structures similar to the said 1st Embodiment, and abbreviate | omit detailed description.

  As in the first embodiment, the shutter unit 20 is a slide shutter provided so as to cross the lower part of the internal flow passage in the outlet body 10, and the movable unit 22 is moved by the drive unit 23 with respect to the fixed unit 21. Thus, the lower predetermined range of the internal flow passage can be opened and closed.

  As in the first embodiment, the shutter unit 20 can switch between the open state and the closed state, but the difference is that the open degree in the open state is divided into two stages of the fully open state and the half open state. Further, it is configured to be switchable and operated by the drive of the drive unit 23 controlled by the control unit 80, and switched and adjusted to any one of three states of the fully open state, the half open state and the closed state.

  In detail, the drive unit 23 controlled by the control unit 80 moves the projecting piece 24 in response to the control command, and causes the movable unit 22 to which the projecting piece 24 is attached to slide relative to the fixed unit 21. And the openings of the fixed portion 21 all overlap each other to produce the open portion 25 at the maximum area, and the openings overlap each other with the openings slightly offset, with the area of the open portion 25 being half of the total open state. This is a mechanism for switching between the half-opened state to be produced (see FIG. 14) and the closed state in which the openings deviate from each other and do not overlap at all.

  The shutter unit 20 is switched between the fully open state and the half open state based on the control corresponding to the blowing state set by the user in the control unit 80, and the user of the control unit 80 enters the room. The open state and the closed state can be switched based on the control for performing the preceding air conditioning to the previous indoor space.

The air flow speed of the conditioned air is the smallest in the fully open state of the shutter unit 20, and can be increased each time the shutter unit 20 is switched to the half open state or the closed state.
However, in the closed state of the shutter unit 20, the air flow speed is excessively high to the extent that the air flow can be felt as a draft in the living space of the indoor space, so in the room condition where the user is present in the indoor space, the shutter unit 20 Is set to either the fully open state or the half open state, and the shutter unit 20 is switched to the closed state only when the user performs the preceding air conditioning on the indoor space before entering the room.

  As in the first embodiment, the guide vanes 30 have a substantially thin plate shape and are disposed in a plurality so as to be tiltable in the vicinity of the other opening 12 in the blowout main body 10. While the direction can be adjusted by moving the connecting plate 33 upward or downward via the control unit 32, the blade inclination angle as the obliquely oriented state can be further switched in two stages as a different point, and the control unit The drive unit 31 controlled at 80 is configured to be switched and adjusted to any one of three states, that is, the horizontal state and the two diagonal states.

  In detail, the drive unit 31 controlled by the control unit 80 tilts the arm 32 in response to the control command, and moves the connecting plate 33 connected to the arm 32 up or down. The respective guide vanes 30 connected to each other are inclined to make the whole blade almost horizontal, the first oblique direction in which the whole blade is inclined by about 21 ° from the position of the lateral state, and the whole blade This is a mechanism for switching to a second oblique orientation which is inclined by about 52 ° from the position of the horizontal orientation.

  The guide vanes 30 can be switched between the sideways state and the first diagonally facing state based on the control corresponding to the blowing state set by the user in the control unit 80, and the user of the control unit 80 can It is possible to switch between the second diagonally oriented state and the other two states based on the control for performing the preceding air conditioning to the indoor space before entering the room.

  The blow-off direction of the conditioned air guided by the guide vanes 30 is lower at every switching of the guide vanes 30 from the horizontal direction in the lateral direction of the guide vanes 30 to the first oblique state and the second oblique state. You can be closer.

  However, in the second obliquely facing state of the guide vanes 30, the air flow of the conditioned air guided by the guide vanes 30 and blown out obliquely downward mainly progresses to the living area below the indoor space, and the air flow of the conditioned air is occupied In the existing state where the user is present in the indoor space, the guide vanes 30 are in the sideways state and the first oblique state, since an excessive downward velocity component is left to the extent that they are felt as a draft in the area. The guide vanes 30 are switched to the second diagonally oriented state only when the air conditioning is performed in advance to the indoor space before the user enters the room.

  The control unit 80 sets the shutter unit 20 in the blowout main body 10 in the two states of the fully open state and the half open state according to the blowing state set by the user inside the room through the operation of the operation switch 81. In addition to switching adjustment to any of them, the guide vanes 30 are switched to any one of the two states of the horizontal state and the first diagonal state. The control unit 80 also performs control related to leading air conditioning by performing air conditioning prior to the room space before the user enters the room and adjusting the indoor environment at the time of entering the room.

  Specifically, when the control unit 80 receives the leading air conditioning instruction information from the central control unit 90 as the external control means as the leading air conditioning to the indoor space, the control unit 80 closes the shutter unit 20 and As the second diagonal state, control is performed to obtain an air harmony state in which the conditioned air blown out obliquely downward from the opening 12 directly reaches the living area in the indoor space as an air flow.

  Under the control of the control unit 80, the shutter unit 20 is closed as the leading air conditioning, and the guide vanes 30 are secondarily directed obliquely from the side orientation, and the other opening of the outlet body 10 The conditioned air whose air flow speed is increased from 12 is guided by the guide vanes 30 and blown downward obliquely downward, and if the user is present in the indoor space, the conditioned air flow is occupied Air conditioning is performed in a blowout state where the living area below the indoor space is reached at a high air flow speed, which corresponds to the extent that it is felt as a draft in the area.

  Thereby, the diffusion of the conditioned air accompanying the mixing of the conditioned air and the indoor air in the living area proceeds rapidly, and the temperature of the indoor air is efficiently raised or lowered in a short time to shift to the set temperature of the air conditioning When the user enters the indoor space (the cabin), a state in which the indoor air has reached the set temperature is obtained, and the comfort of the indoor space can be enhanced to improve the user's satisfaction.

  The control of the central control unit 90 to send the preceding air conditioning instruction information to the control unit 80 is performed based on the determination information that the user enters the indoor space (guest room) after a predetermined time, but this determination information For example, the fact of the user's check-in, which can be obtained at the front of a hotel, can be used. In detail, for example, the user may not act as scheduled according to the reservation schedule of the user, and the user may not actually enter the indoor space, but the check-in at the front desk has been made. In case the check-in user checks the user on the basis that it is customary to enter the indoor space (room) at least after a predetermined time (eg several minutes to a few minutes) to reach the room from the reception In fact can be treated as final information of the user entering the indoor space.

  In addition, before the user enters or enters the indoor space (guest room), the control unit 80 detects that the user is entering the room, more specifically, just before the user enters the indoor space. At the same time, the shutter unit 20 is switched from the closed state to the open state (full open state or half open state), and the guide vanes 30 are switched from the second diagonal state to the first diagonal state or lateral state. Control is performed such that the flow of conditioned air blown out does not directly reach the living area in the indoor space.

  As a result, in the room condition after the user enters the indoor space, the execution of the preceding air conditioning erroneously continues, and the air flow of the conditioned air blown into the indoor space reaches the living area, and a draft for the user It prevents you from becoming uncomfortable.

  Acquisition of the situation immediately before the user enters the indoor space in the control unit 80 is, for example, the check of the user obtained as the central control unit 90 as confirmation information for the user to enter the indoor space after a predetermined time Based on the information related to the fact of In, while counting the elapsed time from the time of check-in, this control unit 80 or central control unit 90, until the user reaches the front of the indoor space from the check-in point The estimated movement time is calculated in advance based on the movement distance, the walking speed, etc., and the time when the counted elapsed time reaches the estimated movement time is acquired by the procedure of immediately before the user enters the room. it can.

  In addition, acquisition of the fact of the user's entry into the indoor space by the control unit 80 is, for example, the door opening / closing operation of the user's entry into the indoor space (guest room) previously installed in the indoor space or the vicinity thereof. It is possible by connecting detection means such as a door sensor or switch to be detected based on the detection unit such as a human sensor inside the room to detect room entry based on the user's indoor detection based on detection by the control unit 80 is there.

  If a security system 110 is additionally provided to monitor the presence of a room with a human sensor or a motion sensor or the like and security control such as a door lock for the indoor space (guest room), the control unit 80 directly communicates with the security system 110. Alternatively, it may be communicably connected via the central control unit 90 to make it possible to obtain the fact of entry from the presence detection information, information related to unlocking, and the like. In this case, it is not necessary to separately provide a detection unit related to the room entry of the user.

  The control unit 80 is further connected to an operation switch 81 provided in the indoor space for receiving an input operation of the user, whereby the shutter portion 20 of the outlet device 1 and the guide vanes are based on the blowing state set by the user. It is a mechanism that can perform 30 adjustment control.

  In addition, the control unit 80 is capable of acquiring information on the room temperature and the outside air temperature, and controls each part of the blowout device so as to be in an appropriate blowout state based on the acquired temperature information. On the other hand, the control unit 80 has a function of determining whether to perform leading air conditioning as heating or cooling based on the difference between the indoor temperature and the outside air temperature. When acquiring information on room temperature and outside air temperature by the control unit 80, a sensor 82 for detecting the room temperature and a sensor 83 for detecting the outside air temperature are provided, and these sensors and the control unit 80 are directly connected to acquire information. In addition to the configuration, information may be obtained from other existing devices that handle such temperature information.

  And since the control part 80 can acquire the information of indoor temperature and can judge whether indoor temperature has reached the setting temperature of air conditioning, the time immediately before a user enters an indoor space, and a user's If it is determined that the room temperature has reached the set point of air conditioning prior to the detection of entering the room, the air flow of the conditioned air does not directly reach the living area from the preceding air conditioner when the set temperature is reached, It is also possible to switch to air conditioning corresponding to the occupancy status of the user. In this case, since the air conditioning state can be reliably switched prior to entering the room, the point in time immediately before entering the room after use by the user or use is based on an incorrect estimate of the user's estimated travel time. Due to a failure in the detection of entering the room, it is possible to avoid the risk of giving discomfort to the user in the room by continuing the preceding air conditioning despite the fact that the user is entering the room.

  In addition, when the air conditioner 200 that supplies the conditioned air to the outlet device 1 corresponds to each indoor space (guest room), the control unit 80 controls the air conditioner 200, for example, the temperature of the conditioned air. Alternatively, it can also serve as an air conditioner control unit that performs control related to adjustment of the air volume.

  In that case, the control unit 80 can obtain information on the indoor temperature and the outdoor temperature from a sensor for detecting an indoor temperature and a sensor for detecting an outdoor temperature provided for air conditioner control, and the obtained indoors From the difference between the temperature and the outside air temperature, in addition to the control of the air conditioner 200, it is also determined whether heating or cooling is to be performed as the leading air conditioning. When the control unit 80 controls the air conditioner 200, instead of the opening adjustment control of the shutter unit 20 in the air outlet apparatus 1, the blowing speed of the conditioned air in the air outlet apparatus changes on the air conditioner side. Adjustment control of a fan or the like can also be performed.

  On the contrary, even when the air conditioner 200 is centrally managed on the building side, for example, in a hotel or the like, and controlled separately from the outlet apparatus 1, the control unit 80 controls the air from the control information of the air conditioner 200. It can also be used to control the air outlet 1 by acquiring whether the conditioning is performed by heating or cooling.

  The central control unit 90 is a computer including a CPU, a storage unit, an input / output interface and the like as its hardware configuration, and operates the computer as the central control unit 90 by a program stored in the storage unit. is there.

  When the guest room management system 100 is an existing computer that functions as a database or the like for information management at the front of a hotel, the central control unit 90 is provided as a function additionally realized by a computer forming the guest room management system 100. It can also be done. Conversely, the computer system forming the central control unit 90 may double as a guest room management system. In addition, when the function of the guest room management system 100 is provided by a server on the network (the various information related to the hotel is managed and operated by so-called cloud computing), the central control unit 90 makes reservation information via the network. The information such as the scheduled check-in time based on the reservation information can be acquired by referring to FIG.

  In addition, when the room management system 100 recognizes and manages the entry of the user (customer) into the indoor space (guest room) through a human sensor or the like, the central control unit 90 uses information relating to such entry. It is possible to obtain and use it for the entrance determination in the control unit 80. Also in this case, it is not necessary to separately provide a detection unit related to the entrance of the user.

  The central control unit 90 sends the preceding air conditioning instruction information to the control unit 80 at the time of obtaining the fact that the user has checked in as the confirmation information of entering the room, so that the preceding air for the indoor space can be taken Although harmonization is started, it is not limited to this, but based on the check-in scheduled time acquired from the reservation information, a predetermined advance air conditioning start time prior to that, that is, the scheduled entrance time in the precedent air conditioning Set a start time that can ensure a sufficient time to reach the set temperature before sending the preceding air conditioning instruction information to the control unit 80 of the target outlet device at the beginning of the preceding air conditioning, and the actual check Preceding air conditioning may be started prior to the inning, and if the user is checking in at the scheduled check in time according to the schedule of reservation, the indoor space will be assured Wait for the entry on which to reach the set temperature is obtained, it can be made more reliable the comfort of the interior space for the user.

Next, the blowout control in the outlet apparatus according to the present embodiment will be described using the flowcharts of FIGS. 15 to 17.
As a premise, the control unit 80 performs control on only the air outlet apparatus 1 independently of the control of the air conditioner 200. The air conditioner 200 automatically supplies conditioned air of an appropriate temperature to the outlet device 1 in the case of indoor temperature conditions that require heating or cooling. Further, it is assumed that the control unit 80 directly obtains information related to the room temperature and the outside air temperature from the indoor and outdoor sensors 82 and 83 that detect these.

  Furthermore, when the entry of the user into the indoor space is detected, the control unit 80 performs control to end the preceding air conditioning and switch to the air conditioning corresponding to the normal user presence condition, About acquisition of the fact of the user's entrance into the space, through the central control unit 90, the existing security system 110 and the control unit 80 of the hotel using the door lock provided on the door of the indoor space (guest room) It is possible to connect and obtain the fact of entry from the information related to unlocking.

  First, the control unit 80 determines whether or not the permission signal for controlling the preceding air conditioning for each indoor space (guest room) is input from the central control unit 90, that is, for the preceding air conditioning for each indoor space (guest room). It is determined whether execution is permitted (step S001).

Here, when the control permission signal is input, the control unit 80 determines whether the room temperature is out of the range of the set temperature which can be regarded as comfortable, which is a standard for performing air conditioning (step S002).
If the room temperature is out of the above range, next, the control unit 80 determines whether the room temperature is lower than the set temperature range to be heated (step S003).

  When the room temperature is a temperature to be heated that is lower than the above range, the control unit 80 sets the air conditioning state to the heating mode, and the conditioned air supplied from the air conditioner 200 is adjusted to the temperature for heating Handle (step S004).

  Subsequently, the control unit 80 receives an input to the control unit 80 of the leading air conditioning instruction information sent from the central control unit 90 based on the fact that the room entry has been confirmed by the user's check-in procedure or the like corresponding to the indoor space. It is determined whether or not it has been made (step S005).

When the advance air conditioning instruction information is input, the control unit 80 corresponds to the air conditioning of each mechanism of the air outlet device, in detail, with the shutter unit 20 closed and the guide vanes 30 in the second oblique state. The orientation state is set (step S006).
At this time, since the air conditioner 200 supplies conditioned air at an appropriate temperature, leading air conditioning is performed.

  Then, the control unit 80 determines whether the user has entered the indoor space based on the information related to the unlocking of the door lock from the security system 110 (step S 007).

If the user has entered the room, the control unit 80 determines whether the operation switch 81 has received an operation by the user (customer) (step S008).
When the operation switch 81 receives an operation, the control unit 80 causes each mechanism of the air outlet device to be in the blowout state set by the operation switch 81 (step S 009).

Thereafter, the control unit 80 determines whether or not the user (user) has checked out based on the management information of the guest room management system 100 obtained through the central control unit 90 (step S010). If the user checks out here, the series of processing ends.
If the user has not checked out at step S010, the process returns to step S001 and the subsequent processing is repeated.

  When the operation switch 81 has not received the user's operation in step S008, the control unit 80 sets the respective mechanisms of the outlet device to the initial setting state for normal heating corresponding to the time when the user is in the room, details In step S011, the guide vanes 30 are in the first oblique orientation state when the shutter unit 20 is fully open. Thereafter, the process proceeds to step S010.

  If the user has not entered the room in step S007, the control unit 80 repeats the determination process of step S007. In step S005, when the preceding air conditioning instruction information is not input, the process proceeds to step S008, and the subsequent processes are repeated.

  If the room temperature is not lower than the set temperature range but high at step S003, the control unit 80 sets the air conditioning state to the cooling mode, and the conditioned air supplied from the air conditioner 200 is cooled. It handles as what is adjusted to the temperature for (step S012).

  Subsequently, based on the fact that the user has entered the room by check-in procedure or the like corresponding to the indoor space, control unit 80 receives input of the leading air conditioning instruction information from central control unit 90 to control unit 80. It is determined whether or not it is (step S013).

  When the leading air conditioning instruction information is input, the control unit 80 causes the respective mechanisms of the outlet device to correspond to the leading air conditioning of cooling, in detail, as described above, with the shutter unit 20 closed. Is in the second diagonally oriented state (step S014).

At this time, since the air conditioner 200 supplies conditioned air at an appropriate temperature, leading air conditioning is performed as cooling.
Then, the control unit 80 determines whether the user has entered the indoor space based on the information related to the unlocking of the door lock from the security system 110 (step S015).

If the user has entered the room, the control unit 80 determines whether the operation switch 81 has received an operation by the user (step S016). When the operation switch 81 receives an operation, the control unit 80 causes each mechanism of the outlet device to be in the blown state set by the operation switch 81 (step S017).
Thereafter, the process proceeds to step S010, where it is determined whether the user has checked out.

  In step S016, when the operation switch 81 has not been operated by the user, the control unit 80 sets the respective mechanisms of the outlet device to the initial setting state for normal cooling corresponding to the time when the user is in the room; In detail, the shutter blade 20 is in the fully open state, and the guide vane 30 is in the sideways state (step S018). Thereafter, the process proceeds to step S010.

If it is determined in step S015 that the user has not entered the room, the control unit 80 repeats the determination process of step S015.
If it is determined in step S013 that the preceding air conditioning instruction information has not been input, the process proceeds to step S016 to repeat the subsequent processing.

  In step S002, when the room temperature is not out of the set temperature range, the control unit 80 sets the air conditioning state to the air blowing mode, and the control unit 80 sets the air conditioning mode to the conditioned air supplied from the air conditioner 200, in particular. It handles as what is not adjusted (step S019).

Subsequently, control unit 80 determines whether or not operation switch 81 has received an operation by the user (step S020). When the operation switch 81 receives an operation, the control unit 80 causes each mechanism of the blowout device to be in the blown state set by the operation switch 81 (step S021).
After that, the process proceeds to step S010, where it is determined whether the user has checked out.

  When the operation switch 81 has not received the user's operation in the step S021, the control unit 80 sets the respective mechanisms of the air outlet device to the initial setting state for normal air blowing corresponding to the time when the user is in the room; For example, when the shutter unit 20 is in the fully open state, the guide vanes 30 are in the sideways state (step S022). Thereafter, the process proceeds to step S010.

  In step S001, when the control permission signal related to the preceding air conditioning is not input to the control unit 80, the control unit 80 determines from the range of the set temperature that the room temperature can be regarded as comfortable, which is an indication of air conditioning execution. It is determined whether it is out (step S023).

If the room temperature is out of the range, then the control unit 80 determines whether the room temperature is lower than the set temperature range to be heated (step S024).
When the room temperature is a temperature to be heated that is lower than the above range, the control unit 80 sets the air conditioning state to the heating mode, and the conditioned air supplied from the air conditioner 200 is adjusted to the temperature for heating Handle (step S025).

  Then, the control unit 80 sets the respective mechanisms of the outlet device to the initial setting state for normal heating corresponding to the time when the user is in the room, in detail, with the shutter portion 20 fully open, the guide vanes 30 One oblique orientation state is established (step S026). Thereafter, the process proceeds to step S010.

  If the room temperature is not lower than the set temperature range but high at step S024, the control unit 80 sets the air conditioning state to the cooling mode and the conditioned air supplied from the air conditioner 200 is cooled It handles as what is adjusted to the temperature for (step S027).

  Then, the control unit 80 sets the respective mechanisms of the blowout apparatus to the initial setting state for normal cooling corresponding to the time when the user is in the room, in detail, the shutter blade 20 is fully open and the guide vanes 30 face sideways The state is set (step S028). Thereafter, the process proceeds to step S010.

  In step S 023, when the room temperature is not out of the set temperature range, the control unit 80 sets the air conditioning state to the ventilation mode, and the conditioned air supplied from the air conditioner 200 has a particularly high temperature. It handles as what is not adjusted (step S029).

  Then, the control unit 80 sets the respective mechanisms of the outlet device to the initial setting state for normal air blowing corresponding to the time when the user is in the room, for example, the shutter blade 20 is fully open, (Step S030). Thereafter, the process proceeds to step S010.

  In the blowout control of the blowout apparatus, the control unit 80 switches the air conditioning from the preceding air conditioning to the air conditioning corresponding to the normal user presence based on the detection of the user's entry into the indoor space, The entry of the user is to grasp the fact of entry from the information related to the unlocking of the security system 110. However, the present invention is not limited to this, the control unit 80 at the time immediately before the user enters the indoor space, Preceding air conditioning shall be switched to an air conditioning state corresponding to the normal user presence state, and acquisition of the situation immediately before the user enters the indoor space shall obtain information on the fact of the user's check-in. The control unit 80 counts the elapsed time from the time of check-in, and the estimated travel time until the user reaches the front of the indoor space from the check The control unit 80 acquires the value calculated by the central control unit 90 based on the line speed and the like, and handles the time when the counted elapsed time reaches the predicted movement time as the time immediately before the user enters the room It can also be done.

  In addition, when the detected indoor temperature reaches the set temperature of air conditioning before detection of the user's entry into the indoor space or before reaching the time immediately before the user enters the indoor space, the control unit 80 At that time, the switching from the preceding air conditioning to the air conditioning corresponding to the normal user presence condition may be performed.

  Subsequently, the conditioned air blowing state in the air outlet apparatus according to the present embodiment will be described. As a premise, it is assumed that the conditioned air is continuously supplied from the air conditioner 200 to the blowout apparatus 1 through the duct 61.

  When the leading air conditioning instruction information is input, the control unit 80 controls the operation of the drive unit 23 of the shutter unit 20 and the drive unit 31 of the guide vanes 30 to advance the opening degree of the shutter unit 20 and the direction of the guide vanes 30. Switch to a state compatible with air conditioning.

  Specifically, if it is necessary to switch the shutter unit 20 from the open state to the closed state when the blowout state of the blowout device is set to correspond to the preceding air conditioning, based on the control of the control unit 80. The drive unit 23 of the shutter unit 20 is operated to linearly move the projecting piece 24 connected to the drive unit 23 and slide the movable unit 22 of the shutter unit 20 integral with the projecting piece 24 with respect to the fixed unit 21. Then, the shutter unit 20 is switched to the closed state.

  In addition, as for the direction of the guide vanes 30, when it is necessary to switch from the previous direction to the second diagonal state corresponding to the preceding air conditioning, the drive unit 31 operates based on the control of the control unit 80. The arm 32 is tilted, the connecting plate 33 connected to the arm 32 of the drive unit 31 is moved upward, and each guide vane 30 whose end is connected to the connecting plate 33 is tilted around its tilting central axis. As a result, the guide vanes 30 are switched to the second obliquely oriented state.

  A blowout state will be described in the case where the shutter unit 20 is in the closed state and the guide vanes 30 are in the second obliquely facing state, corresponding to the leading air conditioning (see FIGS. 18 and 19). In this case, the conditioned air sent from the duct 61 passes through one opening 11 of the outlet body 10 and reaches the shutter portion 20 and the resistor 50, but the conditioned air can not pass through the shutter portion 20 in the closed state, It passes only the resistor 50.

  For this reason, the conditioned air passes through the resistor 50 and passes through the upper flow path portion of the internal flow path in the outlet body 10 above the partition 40, and the cross-sectional area of the flow path through which the conditioned air passes is The passage speed of the conditioned air is increased by making the flow path narrower than when passing through the entire internal flow passage, and the conditioned air having the increased flow rate reaches the guide vanes 30.

  The conditioned air that has reached the guide vanes 30 changes its traveling direction obliquely downward by each of the guide vanes 30 in the second obliquely oriented state. In addition, at this time, the conditioned air passes through only the flow passage portion on the upper side of the partition portion 40 of the inner flow passage while increasing the flow velocity, but does not pass through the flow passage portion on the lower side of the partition portion 40. For this reason, in the flow path portion on the lower side of the partition portion 40, the pressure is relatively reduced with respect to the flow path portion on the upper side, and the advancing air flow of conditioned air is attracted to the region where the pressure is lowered. The downward flow of conditioned air will be promoted as

  Thus, the conditioned air proceeds obliquely downward from the flow passage portion on the upper side of the partition portion 40 of the inner flow passage, passes between the obliquely oriented guide vanes 30, and makes the traveling direction obliquely downward, The air is blown into the indoor space 70 from the region from the top to the center.

  Further, the upper and lower guide vanes 30 in the blowout body 10 are in contact with the inner peripheral surface of the blowout body 10 in the second oblique orientation, so that the guide vanes 30 and the blowout body The air flow of the conditioned air can be prevented from falling through the gap with 10, and the progress of the lower side of the air flow can be promoted, and the conditioned air can be blown downward obliquely at an angle of 60 ° from the horizontal direction.

  When the shutter portion 20 is in the closed state and the guide vanes 30 are in the second diagonal state and in the blowing state related to the preceding air conditioning, warm conditioned air is By increasing the blowing speed and blowing downward obliquely downward, the conditioned air that is warmer than room air can be made to reach the living area of the indoor space without immediately rising, and the living area of the indoor space The conditioned air is mixed with the room air and diffused rapidly, so that the temperature of the living area can reach the set temperature at the normal heating efficiently in a short time.

  In addition, this precedent air conditioning is applicable not only to heating but also to cooling, and by causing cold conditioned air with an increased blowing speed to reach the living area, the living area can be efficiently done in a short time as in the case of heating. Can reach the set temperature for normal cooling.

  When the user enters the indoor space, the control unit 80 controls the operation of the drive unit 23 of the shutter unit 20 and the drive unit 31 of the guide blade 30, and the degree of opening of the shutter unit 20 and the direction of the guide blade 30 Is switched to the state corresponding to the normal room state different from the case of the prior air conditioning. That is, the shutter unit 20 is switched from the closed state to the fully open state or the half open state, and the guide vanes 30 are switched from the second diagonally oriented state to the first diagonally oriented state or laterally oriented state. The condition that the air flow does not reach the living area directly prevents the air flow of the conditioned air from drafting to the user.

  Then, in the presence state where the user enters the indoor space and stays in the indoor space as it is, as in the first embodiment, the control unit according to the blowing state of the outlet device set by the operation of the user 80 controls the operation of the drive unit 23 of the shutter unit 20 and the drive unit 31 of the guide blade 30, and switches the degree of opening of the shutter unit 20 and the direction of the guide blade 30.

  Specifically, when the blowout state of the outlet device is set by the operation of the user, it is necessary to switch the degree of opening of the shutter unit 20 from the state up to that point corresponding to the set blowout state. The drive unit 23 of the shutter unit 20 operates based on the control of the control unit 80, linearly moves the projecting piece 24 connected to the driving unit 23, and the movable unit 22 of the shutter unit 20 integral with the projecting piece 24 moves. Is slid relative to the fixed portion 21 to switch the shutter portion 20 to a predetermined open state different from the previous one, corresponding to the content of the new air conditioning to the indoor space.

  In addition, when it is necessary to switch the direction of the guide vanes 30 from the previous direction according to the set blowout state, the drive unit 31 operates to control the arm 32 based on the control of the control unit 80. Tilting, moving the connecting plate 33 connected to the arm 32 of the drive unit 31 up or down, and tilting each guide vane 30 whose end is connected to the connecting plate 33 around its central axis of tilting Then, the guide vanes 30 are switched to a predetermined direction different from the previous one, corresponding to the content of the new air conditioning to the indoor space.

  According to the setting of the blowout state, in the state where the shutter portion 20 is fully opened and the guide vanes 30 are in the horizontal direction (see FIGS. 4 and 5), the conditioned air sent from the duct 61 The air enters the outlet body 10 from one of the openings 11 of 10. The conditioned air reaches the shutter portion 20 and the resistor 50 in the outlet body 10.

  The conditioned air passes through both the shutter unit 20 and the resistor 50 in the fully open state, and in the upper flow passage portion and the lower flow passage portion sandwiching the partition portion 40 of the inner flow passage in the outlet body 10 A guide vane 30 located closer to the indoor space is reached through both.

  The conditioned air reaching the guide vanes 30 travels between the guide vanes 30 arranged in the vertical direction and is guided by the respective guide vanes 30 turned sideways, the traveling direction is made horizontal, and the interior of the other opening 12 is substantially indoors. The air is blown into the space 70.

  The state where the shutter portion 20 is fully open and the guide vanes 30 are sideways, and the conditioned air is blown out horizontally from almost the entire area of the other opening 12 is mainly used at the time of cooling, By blowing the cold air horizontally from the outlet device provided in the lower ceiling portion 65, it is possible to allow the indoor space to reach a distant place without immediately lowering the cold air heavier than the room air.

  In addition, by not narrowing the flow path of the conditioned air and not increasing the blowing speed excessively, it is surely prevented that the flow of cold air reaches the living area and becomes a draft without reducing the speed when the indoor space is narrow. it can.

  Subsequently, according to another setting of the blowing state, a state in which the shutter unit 20 is in the half open state and the guide vanes 30 are in the horizontal direction will be described (see FIGS. 20 and 21). In this state, the conditioned air sent from the duct 61 passes through one opening 11 of the blowout body 10 and reaches the shutter portion 20 and the resistor 50 in the same manner as described above.

  Although the conditioned air passes through both the shutter unit 20 and the resistor 50 in the semi-opened state, the shutter unit 20 is in the semi-opened state, and the opening area of the open portion 25 through which the conditioned air passes is the fully opened state. The flow velocity of the conditioned air passing through the shutter unit 20 and the resistor 50 is increased by reducing the size of the air conditioner. The conditioned air whose flow velocity is increased reaches the guide vanes 30 through both the upper flow path portion and the lower flow path portion sandwiching the partition portion 40 in the inner flow path in the blowout main body 10.

  The conditioned air that has reached the guide vanes 30 travels horizontally with the direction of travel as it is by the laterally oriented guide vanes 30. At this time, the conditioned air is in a state in which the flow velocity is increased as the shutter unit 20 is in the half open state, but the guidance by each guide vane 30 is the same as the case where the shutter unit 20 is in the completely open state. The air is blown out from almost the entire area of the other opening 12 into the indoor space 70.

  A state in which the shutter portion 20 is half open and the guide vanes 30 are sideways and the conditioned air is blown out horizontally from the other opening 12 is also mainly used at the time of cooling, and the falling ceiling portion By blowing cold air from the air outlet device provided at 65 and increasing the blowing speed horizontally, the cold air that is heavier than room air can be made to reach the far end of the indoor space along the ceiling without lowering it. Even when the indoor space is wide, the cooling air can be efficiently diffused by diffusing cold air into the entire indoor space, and the cooling effect can be reliably obtained.

  Further, according to still another setting of the blowing state, a state in which the shutter portion 20 is in the half open state and the guide vanes 30 are in the first oblique direction will be described (see FIGS. 22 and 23). In this state, the conditioned air sent from the duct 61 passes through the one opening 11 of the outlet body 10 and reaches the shutter portion 20 and the resistor 50, so that both the shutter portion 20 and the resistor 50 in the half open state are pass. However, since the shutter portion 20 is in the half open state and the opening area of the open portion 25 through which the conditioned air passes is smaller than that in the full open state, the harmony between the shutter portion 20 and the resistor 50 is achieved. The flow velocity of air increases. The conditioned air whose flow velocity is increased reaches the guide vanes 30 through both the upper flow path portion and the lower flow path portion sandwiching the partition portion 40 in the inner flow path in the blowout main body 10.

  The conditioned air that has reached the guide vanes 30 travels between the guide vanes 30 lined up and down with the flow velocity increased, and is guided by the guide vanes 30 that are directed obliquely, and the traveling direction is directed obliquely downward And blow out into the indoor space 70 from almost the entire area of the other opening 12.

  The state in which the shutter portion 20 is in the half open state and the guide vanes 30 are in the obliquely downward state and the conditioned air is blown out obliquely downward from the other opening 12 is mainly used at the time of heating, and is lowered. Warming air warmer from the air outlet device provided at the ceiling 65 and increasing the blowing speed obliquely downward, so that warm air lighter than room air can be reached far into the indoor space without immediately rising. Even when the indoor space is large, the warm air can be diffused to the entire indoor space to perform heating efficiently, and the heating effect can be reliably obtained.

  Furthermore, according to another setting of the blowing state, the shutter unit 20 is fully opened and the guide vanes 30 are directed obliquely (see FIGS. 24 and 25). In this state, the conditioned air sent from the duct 61 passes through one opening 11 of the outlet body 10 to reach the shutter portion 20 and the resistor 50, and passes through both the shutter portion 20 and the resistor 50 in the fully open state. Then, the guide vanes 30 located closer to the indoor space are reached through both the upper flow passage portion and the lower flow passage portion sandwiching the partition 40 of the inner flow passage in the blowout main body 10.

  The conditioned air that has reached the guide vanes 30 travels between the guide vanes 30 arranged vertically and is guided by each of the guide vanes 30 that is directed obliquely, and the advancing direction is directed obliquely downward, substantially the entire area of the other opening 12 And blow off into the indoor space 70.

  A state in which the shutter portion 20 is in the open state and the guide vanes 30 are in the diagonally downward direction and the conditioned air is blown obliquely downward from almost the entire area of the other opening 12 is also mainly used at the time of heating. By blowing warm air obliquely downward from an outlet device provided at the lower ceiling portion 65, warm air lighter than room air can be reached far into the indoor space without immediately rising, and efficient heating can be performed. .

  Also, by not narrowing the flow path of the conditioned air by the shutter unit 20 and not increasing the blowing speed excessively, when the indoor space is narrow, the warm air stream reaches the living area without lowering the speed and becomes a draft. Can be prevented.

  As described above, in the air outlet apparatus according to the present embodiment, the shutter is controlled based on the control by the control unit 80 as the leading air conditioning when it is determined that the user almost enters the room after the predetermined time. While the portion 20 is in the closed state, the guide vanes 30 are in the second diagonal state in which the conditioned air is guided in the downward blowing direction, and the air flow velocity is increased from the other opening 12 of the outlet body 10 Since the conditioned air is guided by the guide vanes 30 and blown downward to the indoor space and reaches the living area below the indoor space at a high air velocity, it is accompanied by the mixing of the conditioned air and the indoor air in the living area The diffusion of conditioned air proceeds rapidly, and the temperature of the room air can be increased or decreased efficiently in a short time to be transferred to the set point of the air conditioning, making the room space more comfortable when the user enters the room It can be.

  In addition, when the user enters the indoor space, the control unit 80 causes the shutter unit 20 to be in the open state, and the guide vanes 30 are in the horizontal state or in the first oblique state, and the harmony blown out from the opening 12 The air flow of the air does not reach the living area directly, and the air flow of the conditioned air blown out into the indoor space becomes a draft for the user when the user is in the indoor space. As a result, the comfortable condition of the indoor space by the air conditioning is surely obtained.

  Furthermore, because a state in which the indoor space reaches the heating or cooling setting temperature in a short time can be obtained by the leading air conditioning, for example, when applied to a hotel room, it is sufficiently comfortable to start air conditioning after confirming check-in. As in the case where air conditioning can be performed in advance based on reservation information, if the check-in is delayed from the check-in time of the reservation information, or if there is no check-in, as a result, useless air There is no need to spend harmonious energy, and air conditioning can be implemented efficiently and at low cost. In addition, even if the check-in is earlier than the check-in time of the reservation information, the indoor space can be quickly changed to a comfortable state by the advance air conditioning in a short time, and the user can provide a comfortable indoor space when entering the room. User satisfaction can be enhanced.

  In addition, although the blowing control including execution of the preceding air conditioning in the blower outlet apparatus which concerns on the said embodiment is demonstrated as an example applied to the system of the hotel which made indoor space the hotel guest room, it is not restricted to this It is possible to know in advance that the user's entry into the indoor space to be air-conditioned of the air outlet device is almost certainly performed after a predetermined time, and from the point of grasping this to the actual entry of the user If it is possible to predict the time accurately or if it is possible to detect the entering behavior itself by a predetermined detection means or to obtain the entering information from the existing system, the air outlet apparatus according to the present embodiment is precedent to the indoor space before entering the indoor space Air conditioning can be applied without problems to indoor spaces other than hotel rooms.

  Moreover, in control for execution of the preceding air conditioning in the outlet apparatus which concerns on the said embodiment, after the input operation (also including data reading of barcode etc.) of others including the person in front of a hotel front or a front clerk, check When In is established, the central control unit 90 transmits the preceding air conditioning instruction information to the control unit 80 by using the fact of the check-in as determination information. A method that does not require an operation may be used. For example, when a person enters the building from the outside (or enters into a detectable area of the building), the specific person within the building of the person registered in the database in advance through individual recognition by wireless tag, face image analysis, etc. If the content information associated with the room (such as reserved, staying, staying as a temporary or long-term residence, registered as a member who uses the room, etc.) can be automatically identified, the fact of this identification completion It is possible to transmit the leading air conditioning instruction information to the control unit using the external control means as the confirmation information, and to execute the leading air conditioning to the indoor space of the room.
