Description

  The present invention relates to a circulator for conveying, stirring, and blowing air in an installation space, and a circulator system that operates a plurality of circulators in conjunction with each other.

During operation of air-conditioning equipment, there are many unpleasant air quality conditions such as cold feet accumulating downward during cooling, feet getting cold, and warm air concentrating upward during heating, etc. village). In addition, warm air from solar radiation from windows and attics in the winter tends to accumulate on the ceiling and the upper part of the atrium (temperature unevenness due to natural energy), and the central part of the wide space tends to become dirty and stagnation (stagnation of air circulation) Stagnation). Such a non-uniform air quality situation requires air agitation.
In recent years, there has been a movement to realize energy saving without reducing comfort by reducing the load on air conditioning equipment as much as possible and utilizing natural energy such as solar radiation, ventilation, and cool air on the north side.
As a result, the room air is increasingly stirred by a circulator or a fan, but most of the room air is a floor-standing type and requires installation space (see, for example, Patent Document 1).

Therefore, conventionally, a configuration has been used in which agitating of biased air is performed using a fan or a floor circulator. However, it was only directed in a certain direction, and the air was often not stirred well. In addition, curtains and blinds are opened and closed to open windows, circulate air, and adjust solar energy. In many cases, natural energy cannot be used successfully depending on the weather and outdoor environment. There was no equipment until now.
Furthermore, for effective use of space, it is possible to construct a configuration in which air conditioning and ventilation are transported via a piping duct on the back of the ceiling, which requires extensive installation work, or a fixed ceiling-mounted transport fan (for example, Patent Literature 2 reference / business-use large fixed air conveyance fan, etc.).

In addition, installation of piping ducts and blowers as in the past requires installation of the main unit and piping duct behind the ceiling and under the floor, making the construction large and difficult to install depending on the location. There were restrictions on the installation location.
Furthermore, since the conventional blower devices according to Patent Documents 1 and 2 can change the direction of the wind blown from the blower port to only one of the upper and lower directions and the left and right directions, it is appropriate for the air quality in the installation space. However, depending on the indoor environment, there is a problem that the ventilation is blocked by installation of furniture, furniture, OA equipment, and the like.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing an outline of the internal configuration of the circulator 1 according to the first embodiment, and FIG. 2 shows an external perspective view thereof. The circulator 1 accommodates two line flow fans 11, 12 and sends a blower body 10, an attachment part 20 that is attached to an attachment surface such as a ceiling surface and holds the blower body 10, and the blower body 10. It is comprised from the left-right rotation part 30 which rotates a left-right direction. In the first embodiment, assuming that the mounting surface is an XY axis plane and the direction of gravity with respect to the mounting surface is a Z axis, the left and right rotating unit 20 uses the Z axis as the center axis of the left and right rotation (hereinafter, the left and right rotating shaft). Thus, the blower main body 10 is rotated in the left-right direction.

  The blower body 10 includes line flow fans 11 and 12 that generate airflow, motors 13 and 14 that drive the lineflow fans 11 and 12, and the outside of the blower body 10 to the lineflow fans 11 and 12. An air supply unit 15 (not shown) for taking in air, a blower unit 16 that blows out the generated airflow to the outside, and one end of the left and right rotation unit 30 are connected to one end to rotate left and right, and the blower body unit 10 is moved up and down. And a vertical rotation part 17 that rotates in the direction. The air supply unit 15 and the air blowing unit 16 are configured by appropriately installing a slit, a filter, and the like in an opening portion opened in a case constituting the air blowing main body unit 10.

  The vertical rotation unit 17 includes a main body rotation motor 18 and rotates the blower main body unit 10 about the vertical rotation axis parallel to the XY axis plane so that the air supply unit 15 and the blower unit 16 are moved in the vertical direction. To a predetermined angle. In addition, although the line flow fan is used in the illustrated example, a propeller fan may be used to improve the blowing capacity. Moreover, although it is the structure which provides the motors 13 and 14 for ventilation at the both ends of the ventilation main-body part 10, you may provide one or two motors for ventilation in the center side. Operation control of the blower motors 13 and 14 is performed using a control circuit board (not shown).

  The left / right rotating unit 30 connects one end of the left / right rotating shaft to the main body rotating motor 31 and connects the up / down rotating unit 17 to the other end. The main body rotation motor 31 rotates the left and right rotation shafts to rotate the air supply section 15 and the air blowing section 16 of the air blowing main body section 10 by a predetermined angle in the left-right direction.

  The left / right rotation axis is a first axis parallel to the direction from the mounting portion 20 to the blower body 10, and the up / down rotation axis is a second axis in a direction orthogonal to the first axis. Further, the rotation shaft portion is composed of a vertical rotation portion 17 and a left / right rotation portion 30.

As shown in FIG. 1, the circulator 1 accepts operation information output from a detection unit such as a temperature sensor 41, a stagnation sensor 42, a dust sensor 43, and a human sensor 44 and a remote operation unit (not shown) such as a remote controller. And a remote operation input unit 45.
The temperature sensor 41 is a temperature detection unit including a temperature element, an infrared sensor, and the like, and detects a temperature near the ceiling of the space where the circulator 1 is installed, a temperature of the floor surface, and the like. The stagnation sensor 42 is a stagnation detection unit including a CO ₂ gas sensor, an odor sensor, and the like, and detects stagnation of air. The dust sensor 43 is a stagnation detection unit that includes a light projecting element, a light receiving element, and the like, and detects dust (particle) concentration. The human sensor 44 is a human detection unit configured by the same infrared sensor or the like as the temperature sensor 41 and detects a direction in which a person is present.

  Further, the circulator 1 controls the main body rotation motors 18 and 31 to adjust the vertical and horizontal air blowing directions, and controls the air blowing motors 13 and 14 to adjust the air flow rate (wind speed). It has the control part 50 comprised from these.

Next, the vertical rotation operation of the circulator 1 will be described with reference to FIGS.
3A and 3B are diagrams showing horizontal blowing operation of the circulator 1, in which FIG. 3A is a side view and FIG. 3B is an external perspective view. Assuming that the direction parallel to the XY axis plane is 0 degree horizontal, the vertical rotation part 17 rotates the blower main body part 10 around the vertical rotation axis and directs the blower part 16 to horizontal 0 degree. In this state, the circulator 1 takes in air on the back side of the main body from the air supply unit 15 and blows air from the blower unit 16 toward the front side of the main body.

  FIGS. 4A and 4B are diagrams showing an obliquely downward blowing operation of the circulator 1, FIG. 4A is a side view, and FIG. 4B is an external perspective view. The vertical rotation unit 17 rotates the blower main body unit 10 about the vertical rotation axis, and directs the blower unit 16 obliquely downward 45 degrees. In this state, the circulator 1 takes in the air in the diagonally upward direction on the back side of the main body from the air supply unit 15 and blows it from the air supply unit 16 in the diagonally downward direction on the front side of the main body.

  FIGS. 5A and 5B are diagrams illustrating the air blowing operation of the circulator 1. FIG. 5A is a side view and FIG. 5B is an external perspective view. The vertical rotation unit 17 rotates the blower main body unit 10 about the vertical rotation shaft, and directs the blower unit 16 to 90 degrees below. In this state, the circulator 1 takes in air substantially directly above the main body from the air supply unit 15 and blows air from the air blowing unit 16 in a direction directly below the main body.

  6A and 6B are diagrams showing the air blowing operation directly above the circulator 1, in which FIG. 6A is a side view and FIG. 6B is an external perspective view. The vertical rotation unit 17 rotates the blower main body unit 10 about the vertical rotation axis, and directs the blower unit 16 to approximately 270 degrees directly above. In this state, the circulator 1 takes in air immediately below the main body from the air supply unit 15 and blows air from the air blowing unit 16 in a direction substantially directly above the main body.

  In the illustrated example, the air supply unit 15 and the air blowing unit 16 are formed at opposing positions on the surface of the air blowing main body 10 that are separated by 160 degrees about the vertical rotation axis, but are formed in other positional relationships. For example, they may be formed at opposing positions that are 180 degrees apart.

Next, the horizontal rotation operation of the circulator 1 will be described with reference to FIGS.
FIG. 7 is a top view showing the rotation operation of the circulator 1 in the left-right direction by 180 degrees. If the angular position in the left-right direction of the circulator 1 shown in FIG. 7A is 0 degree in the front, the left-right rotating part 30 rotates the blower body part 10 180 degrees around the left-right rotation axis, and FIG. As shown, the blower 16 is directed to the back at 180 degrees. In the illustrated example, the vertical direction of the blower unit 16 is fixed at 0 degrees horizontally. Needless to say, the vertical direction can be changed simultaneously with the horizontal direction.

  FIG. 8 is a top view showing the 90-degree rotation operation of the circulator 1 in the left-right direction. The blower main body portion 10 facing the front 0 degree indicated by a broken line in FIG. 8 is rotated 90 degrees counterclockwise about the left-right rotation axis so that the left-right rotation section 30 faces the front 90 degrees.

  FIG. 9 is a top view showing the 45-degree rotation operation of the circulator 1 in the left-right direction. The left and right rotating part 30 rotates the air blowing main body part 10 facing the front 90 degrees indicated by the broken line in FIG. 9 45 degrees counterclockwise around the left and right rotation axis to face the front 135 degrees.

  In this way, the circulator 1 rotates the blower unit 16 steplessly clockwise and counterclockwise from the horizontal 0 degrees to approximately 270 degrees above the vertical rotation axis and around the horizontal rotation axis. The blower 16 can be rotated steplessly clockwise and counterclockwise from the front 0 degree to the back 180 degrees. Therefore, the air can be blown in all directions around 360 degrees of the circulator 1 (upward and downward, left and right diagonal directions).

  In the above description, the blower unit 16 is directed to 360 degrees in the vertical and horizontal directions by two-axis rotation of the vertical and horizontal axes using the main body rotation motor 18 of the vertical rotation unit 17 and the main body rotation motor 31 of the left and right rotation unit 30. However, the rotation control method is not limited to this, and for example, the mounting portion 20 and the air blowing main body portion 10 may be connected by a universal joint or the like, and the air blowing portion 16 may be directed to 360 degrees around.

  Next, the operation for each purpose of the circulator 1 will be described. The operation purpose of the circulator 1 is mainly (1) an air conveyance purpose for improving the comfort by conveying air of odor, stagnation of air, uneven temperature in the installation space, and (2) air of uneven temperature. There is an air stirring purpose for uniforming the temperature of the air in the installation space and (3) a variable air blowing purpose for blowing air in an arbitrary direction. Below, the operation example of the circulator 1 is demonstrated according to each objective.

(1) Purpose of Air Transport FIG. 10 is a diagram for explaining the air transport operation of the circulator 1 installed in the installation space 100, FIG. 10 (a) is the state before the operation of the circulator 1, and FIG. 10 (b) is the operation. Indicates the inside state. In the figure, there are windows 101 and 102 opened on a pair of opposing wall surfaces of the installation space 100, and the circulator 1 is installed on the ceiling 103. 10A, when the stagnation sensor 42 detects the stagnation of the air in the installation space 100, for example, the CO ₂ gas concentration representing human breath, the control unit 50 controls the rotation of the blower main body 10 in the vertical and horizontal directions. Then, as shown in FIG. 10 (b), the air blower 16 is adjusted so as to face the direction of the window 102 and become horizontal 0 degree. In the adjusted circulator 1, the air supply unit 15 conveys fresh air from the direction of the window 101 into the installation space 100, and the air blowing unit 16 conveys and discharges air stagnation in the direction of the window 102. The comfort of the space 100 is improved.

  The air supply and transfer destination are not limited to the windows 101 and 102, but may be any opening that allows the installation space 100 and the outside to communicate with each other. Good. In addition to the stagnation of air detected by the stagnation sensor 42, the air conveyance operation includes the conveyance of air at an uneven temperature detected by the temperature sensor 41, the conveyance of dusty air detected by the dust sensor 43, or air conditioning. It can be applied to the transfer of the air to a place where the blown air from the device does not reach.

FIG. 11 is a diagram for explaining another example of the air conveying operation of the circulator 1 installed in the installation space 100. In the figure, the installation space 100 has a south facing window 101 and a north facing window 102. In summer, as shown in FIG. 11A, the temperature sensor 41 detects the cool air on the north side with little solar radiation or the window 102 communicating with the room on the north side, and the control unit 50 rotates the blower body unit 10 in the vertical and horizontal directions. And the direction of the air supply unit 15 and the air blowing unit 16 is adjusted so that the air is blown from the north side to the south side. On the other hand, in autumn and winter, as shown in FIG. 11B, the temperature sensor 41 detects the warm air on the south side with a lot of sunlight or the window 101 communicating with the room on the south side, and the control unit 50 moves the upper and lower sides of the blower main body unit 10. The direction of the air supply part 15 and the ventilation part 16 is adjusted so that rotation in the left-right direction may be controlled to blow air from the south side to the north side.
Thereby, since the temperature difference of the installation space 100 is eliminated and the air conditioning load of the air conditioning equipment can be reduced, energy saving and environmental consideration can be achieved. It also serves as a heat shock countermeasure in winter.

  The operation of the circulator 1 shown in FIG. 11 corresponds to the purpose of (3) variable air blowing described later if the air blowing direction is variable depending on the season.

In this way, by installing the circulator 1 in the home and operating it for the purpose of air conveyance, the air heated by the solar radiation in the south-facing room or the air warmed by the heating equipment is converted into the north-facing room or the heating equipment. It can be transported to a room with no air to make the air uniform. In addition, it can be expected that warm air is transported to the bathroom and dressing room to improve comfort in a space without air conditioning equipment and to relieve heat shock due to temperature difference. In addition, if the hot air in the room is transported toward a ventilation fan, window, etc. when returning home in the summer, ventilation can be maintained even in a living space where wind does not pass, and the air conditioning load can be reduced. In addition, if the air of the cooling device in the adjacent room is transported to a room where the cooling device cannot be installed at bedtime, the cooling air will not directly hit the human body and the comfort will be improved, and the comfort of the space where the cooling device cannot be installed An improvement effect can also be expected.
Of course, the circulator 1 may be installed outside the home, and it goes without saying that the same effect can be obtained by installing the circulator 1 in, for example, a commercial store, an office, or a business space. The same applies to the following (2) and (3).

(2) Purpose of air stirring FIG. 12 is a diagram for explaining the air stirring operation of the circulator 1 installed in the installation space 100, FIG. 12 (a) is a state before the operation of the circulator 1, and FIG. Indicates the inside state. In this example, it is assumed that the air conditioner 104 is in the heating operation. In FIG. 12A, when the installation space 100 detects air whose temperature is biased up and down by the temperature sensor 41, the control unit 50 controls the rotation of the blower main body 10 in the vertical and horizontal directions, and FIG. As shown, the air supply unit 15 is directed substantially directly above, and the air blowing unit 16 is adjusted to 90 degrees below. The adjusted circulator 1 blows down the warm air accumulated in the vicinity of the ceiling 103, stirs the air in the installation space 100, and equalizes the air temperature. This reduces the air conditioning load of the air conditioning equipment 104 and improves comfort.

  When the air conditioner 104 is in cooling operation and cold air is accumulated near the floor of the installation space 100, the air supply unit 15 is directed directly downward and the air blowing unit 16 is adjusted to approximately 270 degrees directly above. It is also possible to blow up the cold that has accumulated near the floor. As a result, the air in the installation space 100 is agitated in the same manner as described above to make the air temperature uniform, thereby reducing the air conditioning load of the air conditioner 104 and improving the comfort.

  In this way, by installing the circulator 1 in the home and operating it for the purpose of air agitation, when the feet just cool down during air-conditioning in the summer and air conditioning in a wide space such as a living room is uneven, toward the floor surface. By blowing air, it is possible to stir the cool air under the feet, bring the whole room to a uniform temperature, reduce the cooling of the feet, and improve comfort. In addition, warm air that tends to collect on the ceiling during heating in the winter can be blown down toward the floor to achieve warm heating to the feet, improving comfort while reducing unnecessary heating equipment operation. it can.

(3) Variable ventilation purpose FIG. 13: is a figure explaining the variable ventilation operation | movement of the circulator 1 installed in the installation space 100. FIG. In the figure, when the person 105 in the installation space 100 is detected by the human sensor 44, the control unit 50 controls the rotation of the blower main body 10 in the vertical and horizontal directions to blow the air toward the person 105 “wind application mode” "Is set, the direction of the blower 16 is adjusted in the direction of the person 105. Further, when the “personnel protection mode” for blowing air while avoiding the person 105 is set, the direction of the air blowing unit 16 is adjusted to the periphery of the person 105. Details of the “breeze mode” and the “personnel protection mode” will be described later.

  As described above, the air blowing direction can be freely changed according to the mode set in the control unit 50, the indoor environment detected by the various sensors, and the like, and various uses can be made. When the circulator 1 is used in a spot in the “air blowing mode” as shown in FIG. 13, the air blows following the location of the person, so that a cool feeling and a refreshing feeling of the wind can be obtained. An electric fan can be substituted, and since it is installed on the ceiling 103, an installation space on the floor is not required, leading to effective use of the space. Also, if the person dislikes the draft feeling, the surrounding air is blown out in the “human protection mode”, so that the surrounding hot air can be eliminated.

  FIG. 14 is a top view for explaining another example of the variable air blowing operation of the circulator 1 installed in the installation space 106. In the figure, when the air conditioner 104 is installed on one end side of the installation space 106 whose floor is L-shaped, the wind of the air-conditioning apparatus 104 is in the space where the L-shape is bent (enclosed by a broken line in the figure). Not reach. Therefore, the circulator 1 is installed at the L-shaped bent position, and the wind of the air conditioner 104 is relayed to the end.

  FIG. 15 is a top view for explaining another example of the variable air blowing operation of the circulator 1 installed in the installation space 107. In the figure, when the air conditioner 104 is installed on one end side of the installation space 107 that is long and long, the wind of the air conditioner 104 does not reach the space on the other end side (enclosed by a broken line in the figure). Therefore, the circulator 1 is installed at a position where the wind of the air conditioner 104 reaches, and the wind of the air conditioner 104 is relayed to the other end side.

  In this way, by installing the circulator 1 in the home and operating it for the purpose of variable ventilation, it can be used in place of a fan in order to relieve heat after taking a bath in the summer or after returning home. Further, in summer / winter, air can be blown so that cold / warm air can reach a Japanese-style room next to the living room without the air-conditioning / heating equipment, a modified living room where the air / air-conditioning equipment cannot reach. Moreover, it can also be utilized as a relay air-conditioning device for distances and places where the wind of the air-conditioning device does not reach, such as L-shaped, trapezoidal, and atrium.

Next, a specific example of the control method of the control unit 50 will be described.
FIG. 16 is a block diagram illustrating a configuration of the control unit 50. The control unit 50 includes a sensor output information acquisition unit 51, a priority purpose determination condition storage unit 52, a priority purpose determination unit 53, a facility / space information storage unit 54, an operation pattern determination condition storage unit 55, and an operation pattern storage. Unit 56, driving pattern determination unit 57, and driving control unit 58.

The sensor output information acquisition unit 51 includes temperature environment information including the temperature of the floor surface of the installation space detected by the temperature sensor 41, the temperature near the ceiling, etc., the CO ₂ gas concentration information and odor information detected by the stagnation sensor 42, The dust concentration information detected by the dust sensor 43 and the human detection information including the presence / absence of the human and the position of the human detected by the human sensor 44 are acquired from each sensor.

  The priority purpose determination condition storage unit 52 is means for storing priority purpose determination information for determining the priority of the operation purpose of the circulator 1, and this priority purpose determination information is preset. When the sensor output information described above is input from the sensor output information acquisition unit 51, the priority purpose determination unit 53 converts the sensor output information and the operation state information of the air conditioner stored in the facility / space information storage unit 54, which will be described later. Based on the priority purpose determination condition storage unit 52, the priority purpose is determined.

FIG. 17 is a diagram illustrating an example of priority purpose determination information stored in the priority purpose determination condition storage unit 52. In this example, there are six types of priority purpose determination conditions 1 to 6, and the priority purpose determination unit 53 is configured based on the sensor output information of the stagnation sensor 42, for example, the condition “determination condition CO ₂ concentration (or odor). If the odor detected by the sensor is higher than the set value, it is determined that this is the case, and the priority purpose is determined to be “elimination of stagnation”. The priority of the “stagnation elimination” is “1”, and when a plurality of priority purposes correspond to the sensor output information, the priority is given the highest priority.
Further, if the dust concentration detected by the dust sensor 43 is higher than the set value, the priority purpose determination unit 53 selects the priority purpose “removal of dustiness”.
Further, if the temperature near the ceiling detected by the temperature sensor 41 is equal to or higher than the set temperature, the priority purpose determination unit 53 selects the priority purpose “elimination of heat”.
In addition, the priority purpose determination unit 53 selects the priority object “cancellation of cooling” if the operation state information of the air conditioner indicates that the cooling operation is being performed and the temperature near the floor detected by the temperature sensor 41 is equal to or lower than the set temperature. To do.
Further, the priority purpose determination unit 53 indicates that the priority object “temperature distribution” is present if the operation state information of the air conditioner indicates that the heating operation is being performed and the temperature difference between the vicinity of the ceiling and the floor detected by the temperature sensor 41 is greater than or equal to an allowable range. Select “Resolve non-uniformity”.
In addition, the priority purpose determination unit 53 is a case where the operation state information of the air conditioner indicates that it is in operation, for example, when the space information indicates an installation space of “L-shaped space” (FIG. 18). If the difference in temperature detected by the floor 41 at two or more locations on the floor is greater than or equal to the allowable range, it is determined that the “distance does not reach” condition and the priority purpose “carrying air for heating and cooling” is selected.

The facility / space information storage unit 54 is a means for storing information on the installation space in which the circulator 1 is installed and information on facility equipment existing in the installation space, and the facility / space information is set in advance.
FIG. 18 is a diagram illustrating an example of facility / space information stored in the facility / space information storage unit 54. In this example, the facility information used as a more detailed determination condition corresponding to the condition of the determination condition 6 in FIG. 17 “when the air for cooling and heating does not reach part of the room” is stored. It is determined from the temperature difference. The space information such as the size and shape of the installation space may be set in the facility / space information storage unit 54 from the remote operation unit 45 via the remote operation input unit 45, or may be configured by an infrared sensor or the like. It is possible to recognize the size of the space more accurately by recognizing the position information of the floor and wall surface from the device installation position using the space recognition sensor (space recognition unit) The shape and the like may be automatically recognized and the information may be set in the facility / space information storage unit 54.

  Further, as the space information, for example, installation positions of openings such as windows, doors, and ventilation fans in the installation space, information on other circulators 1 (details will be described in the second embodiment), other equipment (air conditioning equipment, etc.) ) Has position information indicating the installation position. These pieces of position information may be set in the facility / space information storage unit 54 in advance, or information may be acquired from a remote operation unit such as a remote controller via the remote operation input unit 45. Alternatively, when the above-described space recognition sensor is provided, the position of the window or the like may be automatically recognized and the position information may be stored in the facility / space information storage unit 54.

  FIG. 19 is a diagram for explaining an example of position information of windows, ventilation fans, and the like in the installation space of the circulator 1. In the figure, the installation position of the circulator 1 is the origin of orthogonal X, Y, and Z axes, and the position of the window and the like is the azimuth angle H on the XY axis plane and the elevation relative to the origin on the XY axis plane. It is expressed by a depression angle A and a distance D from the origin. In the illustrated example, there are windows, ventilation fans and the like on the side wall surface of the installation space, but it goes without saying that there may be other air conditioners (air conditioners, other blowers) and the like.

  Furthermore, the facility / space information storage unit 54 also stores operation state information indicating the operation states of other facility devices (such as air conditioners). As the operation state information of the air conditioner, the cooling / heating operation time for each season, that is, the setting information for the schedule operation may be set in the facility / space information storage unit 54 in advance. Alternatively, the operation determination means (not shown) may determine whether or not the air conditioning operation is being performed based on the temperature detected by the temperature sensor 41 and update the operation state information in the facility / space information storage unit 54 as needed. . Alternatively, a communication means (not shown) that communicates with the air conditioner in a wired or wireless manner may directly acquire the operation state information from the air conditioner and update the operation state information in the facility / space information storage unit 54 as needed. .

  Furthermore, the facility / space information storage unit 54 also stores setting mode information of “breeze mode” and “personnel protection mode”. The setting mode information is set in the facility / space information storage unit 54 from the remote operation unit via the remote operation input unit 45, for example.

The driving pattern determination condition storage unit 55 is means for storing driving pattern determination information for determining a driving pattern according to the priority purpose of the circulator 1, and this driving pattern determination information is set in advance.
FIG. 20 is a diagram illustrating an example of driving pattern determination information stored in the driving pattern determination condition storage unit 55. In this example, there are six types of determination conditions 1 to 6 for the operation pattern. For example, as the determination condition 1, the condition of the facility / space condition and the setting mode corresponding to the priority purpose “resolve stagnation” in FIG. The driving pattern to be set is set.

The operation pattern storage unit 56 is a means for storing information related to specific operation control of the circulator 1 according to the operation pattern.
FIG. 21 is a diagram illustrating an example of operation control information corresponding to the operation pattern stored in the operation pattern storage unit 56. In this example, there are four types of operation control information corresponding to the operation patterns 1 to 4 in FIG. 20, and the rotation angle (air blowing direction) and wind speed conditions of the blower main body 10 are set for each operation pattern. ing.

  When the priority purpose is input from the priority purpose determination unit 53, the driving pattern determination unit 57 selects a driving pattern corresponding to the priority purpose from the driving pattern storage unit 56, and sets specific driving control information of the driving pattern. It is determined according to the operation pattern storage unit 56 and output to the operation control unit 58. When the operation control information of the operation pattern is input from the operation pattern determination unit 57, the operation control unit 58 receives the blower motors 13 and 14 and the main body rotation motor based on the facility / space information in the facility / space information storage unit 54. 18 and 31 are controlled.

  For example, when the priority purpose “stagnation elimination (priority 1)” is input from the priority purpose determination unit 53, the driving pattern determination unit 57 selects “driving pattern 1” from the driving pattern storage unit 56. In addition, when the priority purpose “relieving heat (priority 4)” is input, the driving pattern determination unit 57 indicates that the setting mode information stored in the facility / space information storage unit 54 is “wind blowing mode”. “Driving pattern 3” is selected, and “Driving mode” is selected, “Driving pattern 4” is selected.

For example, when the operation pattern 1 is selected, the operation pattern determination unit 57 subsequently acquires position information of the air blowing object such as a window and a ventilation fan from the facility / space information storage unit 54 and determines the vertical and horizontal directions and the wind speed of the air blowing unit 16. Then, operation control information is generated and output to the operation control unit 58.
At this time, the driving pattern determination unit 57 determines the rotation angle in the left-right direction of the main body rotation motor 31 of the left-right rotation unit 30 from the azimuth angle H of the blow object, and determines the vertical rotation of the main body rotation motor 18 of the vertical rotation unit 17. The rotation angle is determined from the elevation angle A of the blown object. Further, the possible air blowing range of the air blowing unit 16 may be set to a fixed value such as a wind speed of 1.5 m / s and the air may be blown into the fixed range, or the wind speed may be variably controlled in multiple stages according to the distance D of the window or the like. The air may be blown within an arbitrary range. In addition, when conveying to the place where the wind of an air conditioner does not reach, it is made to blow in the direction of the place which does not reach.
The operation control unit 58 controls the main body rotation motors 18 and 31 and the blower motors 13 and 14 according to the operation control information, and blows the blower unit 16 toward the window, the ventilation fan, or the like.

Details of each operation pattern will be described with reference to the flowcharts of FIGS. 22 and 23A to 23E.
As shown in FIG. 22, when the circulator 1 starts operation, in step ST1, the temperature sensor 41, the stagnation sensor 42, the dust sensor 43, and the human sensor 44 also start detection operations and output sensor output information.

  In step ST2, the sensor output information acquisition unit 51 acquires sensor output information, and the priority purpose determination unit 53 analyzes the air quality state of the installation space. In step ST3, the priority purpose determination unit 53 prioritizes determination conditions corresponding to the air quality state of the analysis result and the operating state of the air conditioner, etc., from the priority purpose determination condition storage unit 52 and the facility / space information storage unit 54. Select a purpose.

When the priority purpose “elimination of stagnation” is selected (step ST3 “elimination of stagnation”), the operation pattern determination unit 57 selects “operation pattern 1” in the subsequent step ST4, and the operation control unit 58 in the subsequent step ST5. By controlling the vertical and horizontal directions of the blower main body 10, for example, as shown in FIG. 10, stagnation air is conveyed to a window, a ventilation fan or the like and discharged.
As a result, stagnant air that cannot be removed by a normal 24-hour continuous operation type ventilation fan or the like can be transported to an opening of a window, a ventilation fan, or the like and quickly eliminated.

When the priority object “elimination of dustiness” is selected (step ST3 “elimination of dustiness”), the driving pattern determination unit 57 selects “driving pattern 1” in step ST4a shown in FIG. In subsequent step ST5a, the operation control unit 58 controls the vertical and horizontal directions of the blower main body unit 10 to convey dusty air to a window, a ventilating fan or the like and discharge it.
Accordingly, dusty air that cannot be removed by a normal 24-hour continuous operation type ventilation fan or the like can be conveyed to an opening of a window, a ventilation fan, or the like, and quickly eliminated.

When the priority purpose “elimination of heat” is selected (step ST3 “elimination of heat”), in step ST4b shown in FIG. 23B, the driving pattern determination unit 57 determines the person in the installation space based on the human detection information. Determine presence or absence. When there is a person and the “air blowing mode” is set (step ST4b “YES”), the driving pattern determination unit 57 selects “driving pattern 3” in the subsequent step ST5b. In subsequent step ST6b, the operation control unit 58 controls the vertical and horizontal directions of the blower main body 10 so that the blower 16 follows the direction of the person detected by the human sensor 44, for example, as shown in FIG. Then, blow in the direction where people are.
Thereby, it can blow in a spot according to a person's whereabouts, and can obtain a cool feeling of wind and a refreshing feeling quickly. Moreover, since it is not necessary to operate the cooling device, energy saving can be achieved.

On the other hand, in the case where there is no person or “personnel protection mode” is set (step ST4b “NO”), the driving pattern determination unit 57 selects “driving pattern 4” in the subsequent step ST7b. . In subsequent step ST8b, the operation control unit 58 controls the vertical and horizontal directions of the blower main body 10 so that the blower 16 faces a place where there is no person, or a window, a ventilation fan, etc. Air is blown out or blown out to windows, ventilation fans, etc. to discharge hot air.
Thereby, the hot air which cannot be removed immediately by a normal 24-hour continuous operation type ventilation fan or the like can be conveyed to an opening of a window, a ventilation fan or the like and quickly eliminated.

When the priority object “elimination of cold” is selected (step ST3 “elimination of cold”), the operation pattern determination unit 57 selects “operation pattern 2” in step ST4c shown in FIG. 23C, and operation control is performed in the subsequent step ST5c. The part 58 controls the vertical and horizontal directions of the blower main body 10 to blow up cool air accumulated near the floor, for example, as shown in FIG.
As a result, the cooling device is effective in summer, the feet are cold, the overhead is hot, the uneven temperature difference in the vertical direction is improved, and the comfort can be improved. As a result, it is possible to reduce energy consumption by reducing the load on the cooling / heating device and suppressing power consumption.

  When the priority object “resolving uneven temperature distribution” is selected (step ST3 “resolving uneven temperature distribution”), the operation pattern determination unit 57 selects “operation pattern 2” in step ST4d shown in FIG. 23D. To do. In subsequent step ST5d, the operation control unit 58 determines the presence or absence of a person in the installation space based on the human detection information. When there is a person (step ST5d “YES”), the operation control unit 58 sends air so that the air blowing unit 16 faces in the direction in which no human sensor 44 detects in the subsequent step ST6d and in the direction of 90 degrees below. Air is blown by controlling the vertical and horizontal directions of the main body 10, and air is stirred by blowing down the warm air accumulated near the ceiling.

On the other hand, when there is no person (step ST5d “NO”), the operation control unit 58 controls the up / down / left / right direction of the blower main body 10 so that the blower 16 is directed to the direction of 90 degrees below in step ST7d. Then, blow down the warm air collected near the ceiling and stir the air.
As a result, the warmth of the heating device rises upward in winter, and the uneven vertical temperature difference in the state where the lower side where the person is present does not warm up can be improved, and comfort can be improved. As a result, it is possible to reduce energy consumption by reducing the load on the heating device and suppressing power consumption.

When the priority purpose “carrying air for cooling / heating” is selected (step ST3 “carrying air for cooling / heating”), the operation pattern determination unit 57 selects “operation pattern 1” in step ST4e shown in FIG. 23E. In subsequent step ST5e, the operation control unit 58 determines a place where the air-conditioning equipment has not reached the wind based on the facility / space information in the facility / space information storage unit 54 and the temperature environment information detected by the temperature sensor 41. For example, as shown in FIGS. 14 and 15, air is blown by controlling the vertical and horizontal directions of the blow body 10 so that the blower 16 faces.
As a result, it becomes possible to relay the air from the air conditioning equipment to a position where the air blowing distance of the air conditioning equipment does not reach, and to provide comfortable temperature-adjusted air even in places where the air conditioning equipment cannot be installed. The air can be blown.

In addition, in step ST3 shown in FIG. 22, when there are a plurality of priority objectives of the determination condition corresponding to the air quality state of the analysis result, the control unit 50 first performs subsequent processing for the priority objective with the highest priority. Thereafter, the subsequent processing is performed for the priority object having the next highest priority, or the processing may be started again from step ST1.
Moreover, the driving pattern (and driving control information) for each priority purpose described above is an example, and the circulator 1 may cancel the priority purpose by performing other operations.

  As described above, according to the first embodiment, the circulator 1 is supplied from the air supply unit 15 to generate an air flow, and blown from the blower unit 16 and the blower body attached to the ceiling surface of the installation space. Since the mounting portion 20 that holds the portion 10 and the vertical rotation portion 17 and the left-right rotation portion 30 that rotate the air blowing main body portion 10 in all directions of 360 degrees are provided, installation is easy and space is not taken up. In addition, air can be conveyed, stirred, and variable ventilation can be performed in all directions around 360 degrees.

The circulator 1 according to the first embodiment is configured to include the temperature sensor 41, the stagnation sensor 42, the dust sensor 43, and the human sensor 44. However, it is not necessary to include all the sensors, and at least one type of circulator 1 is provided. The structure which provides a sensor and performs only the ventilation operation according to the sensor output information may be sufficient.
Further, the sensor for detecting the air quality is not limited to the temperature sensor, the CO ₂ gas concentration sensor, the odor sensor, and the dust sensor. For example, a humidity sensor may be used.

Embodiment 2. FIG.
In the first embodiment, the example in which one circulator 1 is installed and operated in the installation space has been described. In the second embodiment, an example in which a plurality of circulators 1 are linked will be described. When interlocking a plurality of circulators 1, the operation purpose is mainly (1 ′) interlocked air conveying purpose, (2 ′) interlocked air agitating purpose, and (3 ′) interlocking variable as in the first embodiment. There is a purpose of blowing. Hereinafter, an example of the interlocking operation of the circulator 1 will be described for each purpose. In FIGS. 24 to 28 shown below, the same or corresponding parts as those in FIGS. 1 to 13 are denoted by the same reference numerals and description thereof is omitted.

(1 ′) Interlocked Air Transport Purpose FIG. 24 is a diagram for explaining the air transport interlock operation of a plurality of circulators 1 installed in the installation space 100, and FIG. 24 (a) is a state before the operation of the circulators 1a to 1d. FIG. 24B shows a state during operation. In order to distinguish a plurality of circulators, they are referred to as circulators 1a to 1d, and each has the same configuration as circulator 1 in FIG.

  In FIG. 24A, when the stagnation sensors 42a and 42b of the circulators 1a and 1b in the installation space 100 detect air stagnation, the control units 50a to 50d rotate the air blowing main body units 10a to 10d in the vertical and horizontal directions. To adjust the air blowers 16a to 16d so that they face the window 102 and become 0 degrees horizontally. Each adjusted circulator 1a to 1d conveys fresh air from the direction of the window 101 into the installation space 100 as shown in FIG. 24B, and conveys and discharges air stagnation in the direction of the window 102. To do.

  As in the first embodiment, the air supply and transfer destination is not limited to the windows 101 and 102, and may be a door, a ventilation fan, or the like that communicates the installation space 100 with the outside. In addition to the stagnation of the air detected by the stagnation sensors 42a to 42d, the air conveyance interlocking operation includes the conveyance of the air of the uneven temperature detected by the temperature sensors 41a to 41d and the dusty air detected by the dust sensor 43. It can be applied to the transfer of the air to the place where the blown air from the air conditioner does not reach.

  FIG. 25 is a view showing another example of the air conveyance interlocking operation of the plurality of circulators 1 installed in the installation space 100, FIG. 25 (a) is a state before the operation of the circulators 1a to 1d, and FIG. 25 (b). Indicates the operating state. In summer, as shown in FIG. 25 (a), hot air tends to accumulate around the south window 102, and conversely, the temperature around the north window 101 tends to be low. When the temperature sensors 41a and 41d of the circulators 1a and 1d in the installation space 100 detect a temperature difference of a predetermined range or more, the control units 50a to 50d control the rotation of the blower main body units 10a to 10d in the vertical and horizontal directions. As shown in FIG. 25 (b), the air blowers 16 a to 16 d are adjusted to face the direction of the window 102 and become horizontal 0 °. The adjusted circulators 1a to 1d carry air from the direction of the window 101 to the direction of the window 102 as shown in FIG. 25 (b), lower the temperature around the south side window 102 and make the air comfortable. Eject from 102.

  As described above, by causing the plurality of circulators 1 to operate in conjunction with each other for the purpose of air conveyance, the same effect as that of (1) Air conveyance purpose in the first embodiment is obtained. In addition, by installing the circulator system according to the second embodiment in a wide space such as a commercial store, an office, or a business space where the air cannot reach by one circulator 1, and operating it for the purpose of linked air conveyance The air heated by solar radiation in the large office area facing the south or the air heated by the heating equipment is transported to the north office area, or multiple circulators 1 are operated in conjunction in the large office area. If air is transported in any direction, it is possible to equalize uneven warm air in a wide area and warm air that tends to accumulate on the ceiling. In summer / winter, if cool air / warm air is transported from the inside to an area where the temperature is likely to change near the entrance of stores and offices, an effect of improving the comfort of a space without air conditioning equipment can be expected. In addition, in the winter, if warm air is transported from the inside to an area where the temperature is close to the entrance / exit of elderly care facilities and hospitals, the effect of reducing the heat shock due to the temperature difference can be expected. Furthermore, even in offices and business spaces where there are many people, stagnant air can be conveyed to windows, ventilation fans, etc. for ventilation.

(2 ′) Interlocking Air Stirring Purpose FIG. 26 is a diagram for explaining the air agitating interlocking operation of a plurality of circulators 1 installed in the installation space 100, and FIG. 26 (a) is an air conditioner before the operation of the circulators 1a to 1d. FIG. 26B shows a state in which the circulators 1a to 1d are in operation and the air conditioners 104a and 104b are in a cooling operation. FIG. 26C shows that the circulators 1a to 1d are in operation. Indicates the state. 26 (a) and 26 (b), when the temperature sensors 41a to 41d detect air whose temperature is biased up and down in the installation space 100, the control units 50a to 50d are arranged in the vertical and horizontal directions of the blower main body units 10a to 10d. As shown in FIG. 26 (c), the rotation is controlled so that the air blowing parts 16a and 16b of the circulators 1a and 1c are adjusted to 90 degrees directly below, and the air supply parts 15a and 15c are directed substantially right above. Further, the air blowing portions 16b and 16d of the circulators 1b and 1d are adjusted to approximately 270 degrees directly above, and the air supply portions 15b and 15d are directed directly below. Thereby, circulator 1a-1d stirs the air in installation space 100, and eliminates a temperature difference.

  25 (a) and 25 (c) are diagrams showing another example of the air agitation interlocking operation of the plurality of circulators 1 installed in the installation space 100, and FIG. 25 (c) shows the circulators 1a to 1d. The state during operation is shown. In autumn and winter, as shown in FIG. 25 (a), the area around the south facing window 102 with a lot of solar radiation is warm, but the window 101 tends to be cold facing the north side. When the temperature sensors 41a and 41d of the circulators 1a and 1d in the installation space 100 detect a temperature difference of a predetermined range or more, the control units 50a to 50d control the rotation of the blower main body units 10a to 10d in the vertical and horizontal directions. As shown in FIG. 25 (c), the air blowing portion 16a of the circulator 1a is adjusted to approximately 270 degrees directly above, and the air supply portion 15a is directed downward. Further, the air blowers 16b and 16c of the circulators 1b and 1c are adjusted to 0 degrees horizontally. Further, the air blowing part 16d of the circulator 1d is adjusted to 90 degrees directly below, and the air supply part 15d is directed substantially upward. Further, the circulators 1a to 1d are rotated left and right so that the air blowing portions 16a to 16d are directed toward the window 102, respectively. Accordingly, the circulators 1 a to 1 d blow up the cool air accumulated near the floor and blow the warm air accumulated near the ceiling 103 to stir the air, thereby eliminating the temperature difference in the installation space 100.

  As described above, by causing the plurality of circulators 1 to operate in conjunction with each other for the purpose of air stirring, the same effect as that of (2) the purpose of air stirring in the first embodiment is obtained. In addition, by installing the circulator system according to the second embodiment in a wide space where one circulator 1 cannot send air and operating it for the purpose of linked air agitation, the volume in the area is large in summer / winter. When the airflow of the air-conditioning equipment is insufficient and the feet cool down / only overhead is warmed, the air in the area can be agitated and the entire area can be brought to a uniform temperature. Therefore, it is possible to improve the comfort by reducing the coolness of the feet in the summer, and to improve the comfort while reducing the operation of the useless heating device in the winter.

(3 ′) Interlocking Variable Blower Purpose FIG. 27 is a top view for explaining an example of the variable airflow interlocking operation of a plurality of circulators 1 installed in the installation space 108. In the figure, when two air conditioners 104a and 104b are installed in an installation space 108 having an L-shaped floor surface, the air-conditioners 104a, 104a, 104b, etc. The wind of 104b does not reach. Therefore, a plurality of circulators 1a to 1d are installed in the bent position of the L-shape, between the air conditioners 104a and 104b, and the wind of the air conditioners 104a and 104d is relayed to the destination.

  FIG. 28 is a top view for explaining another example of the variable air blow interlocking operation of the plurality of circulators 1 installed in the installation space 109. In the drawing, when two air conditioners 104a and 104b are installed in a trapezoidal installation space 109 that is deformed instead of a normal rectangular parallelepiped shape, the air conditioner is installed in the protruding space (enclosed by a broken line in the figure). The winds 104a and 104b do not reach. Therefore, the circulators 1a and 1b are installed at positions where the wind of the air conditioners 104a and 104b reaches, and the wind of the air conditioners 104a and 104b is relayed to the protruding space.

  As described above, by causing the plurality of circulators 1 to operate in conjunction with each other for the purpose of variable ventilation, the same effect as that of (3) Variable ventilation in the first embodiment is obtained. In addition, by installing the circulator system according to the second embodiment in a wide space such as a commercial store, an office, a business space, etc., where the air cannot reach by one circulator 1, Instead of a fan in a room without air conditioning equipment, a room where the air conditioning equipment cannot be installed because there is no outdoor unit installation location, a room where cooling is not effective, or a temperature zone where the air conditioning equipment does not operate due to energy saving It can be used in a spot-like manner, and the energy saving can be achieved by shortening the operation time of the air conditioner or improving the efficiency of the air conditioning. Further, in summer / winter, air can be blown so that cold / hot air can reach a corridor without air-conditioning / heating equipment, an office area where the air-conditioning / heating equipment does not reach, and the like. Moreover, it can also be utilized as a relay air conditioner for distances and places where the air conditioner does not reach, such as L-shape, trapezoid, and atrium.

  As described above, even when a plurality of circulators 1 are mounted and operated in a wide space, each circulator 1 is installed on the ceiling surface, so that installation space on the floor surface is unnecessary, and commercial stores, offices, business It leads to effective use of space such as business space.

Next, a specific example of the control method of the control unit 50 when a plurality of circulators 1 are operated in conjunction will be described.
Each of the plurality of circulators 1 has a control unit 50. However, in the case of interlocking operation, one of the control units 50 is set as a main control unit, and the other control units 50 are controlled from the main control unit. The sub-control unit that operates according to Therefore, for example, the circulator 1 is provided with switching means for switching the operation setting of the single use mode (corresponding to the first embodiment), the main control mode, and the sub control mode, or the main control device separate from the circulator 1 And the control unit 50 of each circulator 1 is used as a sub-control unit.

Hereinafter, an example in which the four circulators 1a to 1d are operated in conjunction with each other using the main control device will be described. The main controller and each circulator 1a to 1d can communicate with each other by wire or wirelessly.
In addition, it is assumed that the operation settings of the control units 50a to 50d of the circulators 1a to 1d are switched to the sub control mode. The control unit 50 set to the sub control mode transmits the sensor output information to the outside by communication, receives the operation pattern and the operation control information from the outside by communication, and the operation control unit 58 sends air according to the operation control information. The vertical and horizontal directions of the main body 10 are adjusted.

  FIG. 29 is a block diagram illustrating a configuration of the main control device 60. 29, the same or corresponding parts as in FIG. 16 are denoted by the same reference numerals and description thereof is omitted. The main controller 60 communicates with the circulators 1a to 1d in a wired or wireless manner, and the sensor output information acquisition unit 51 of the main controller 60 acquires sensor output information from the circulators 1a to 1d. In addition, the operation control instruction unit 61 instructs the operation control information for the interlocking operation to the control units 50a to 50d of the circulators 1a to 1d.

The interlocking operation of the circulators 1a to 1d controlled by the main controller 60 will be described with reference to the flowcharts of FIGS. 30 and 31A to 31B.
