[0005] Even in conventional floor-blowout air-conditioning systems, there is a demand for a structure that allows easy adjustment of the direction of the conditioned air blown out from the air outlet. A ceiling-mounted air outlet with a fan is generally known as an air outlet that adjusts the air direction. In this case, the air direction is changed manually, but since it is installed on the ceiling, there is a problem that it is difficult to change the air direction on a daily basis. Furthermore, since the installation position of the air outlet is determined by the size and arrangement of the floor panel, there is a problem that the installation position of the air outlet is not always suitable for users, and there is room for improvement in this respect.

[0006] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a floor-blowing air direction adjustment device that can easily adjust the direction of air for conditioning blown out from a floor-blowing type blowing section. [Means for solving the problem]

It is characterized by the fact that

[0008] In the present invention, the wind direction can be easily changed in the direction of rotation around the vertical direction by rotating the rotating operation unit to rotate the multiple inclined blades. In addition, since the rotating operation unit and the multiple inclined blades are supported by the same rotation shaft, this can be achieved with a simple structure. In this way, since the wind direction can be adjusted as desired by the wind direction adjustment device, even if the user's position is misaligned with respect to the blowing unit, for example, the wind direction adjustment device can change the blowing airflow direction to provide conditioned air in the optimal direction for the user, thereby improving the comfort of the user. In this way, in the present invention, the direction of the air for conditioning blown out from the floor-type blowing section can be easily adjusted.

[0009] In addition, the air direction adjustment device for floor air outlet of the present invention may be characterized in that the multiple inclined blades are fixed inside a circumferential frame centered on the rotation axis, the circumferential frame is formed integrally with the rotation axis, and by rotating the rotating operating part, the circumferential frame and the multiple inclined blades rotate integrally.

[0010] In this case, since a plurality of inclined blades are integrally provided on the circumferential frame, the structure is simple and can be easily incorporated into the structural body of a building, such as a floor. Effect of the Invention

[0011] According to the underfloor airflow direction adjustment device of the present invention, the direction of air for conditioning blown out from the underfloor air outlet portion can be easily adjusted. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an airflow direction adjusting device for underfloor air outlet according to an embodiment of the present invention will be described with reference to the drawings.

[0014] An airflow direction adjustment device 10 for underfloor airflow according to this embodiment is installed in a room, such as an office, as shown in Fig. 1, and is provided in an air conditioning control system 1 that blows air for air conditioning toward the room above the floor from multiple air outlets 2 (see Fig. 2) arranged at predetermined positions on the floor. In the air conditioning control system 1, the air conditioning in the room is controlled by operation by an operator M.

[0015] The floor to which the air conditioning control system 1 of this embodiment is applied has a double floor structure in which support members such as joists and support pillars are installed on a floor slab and floor panels 21 are supported by the support members. A plurality of air outlets 2 are provided at predetermined positions on the floor panels 21, which are arranged vertically and horizontally. A carpet, for example, is placed on the floor panels 21. The space between the floor slab of the double floor structure and the floor panels 21 forms an underfloor space (hereinafter referred to as an underfloor chamber 22) through which the air for air conditioning E circulates. The air outlet (cover member 24 described later) of the air outlet unit 2 is formed in a lattice pattern by a plurality of blades arranged at predetermined intervals. The air outlet unit 2 is disposed, for example, near a desk provided at a predetermined location in the room.

[0016] The air conditioning control system 1 comprises a blowing unit 2 equipped with a blowing fan 3, a portable communication terminal 4 that can be carried by an operator M and can operate the blowing fan 3 via communication, a position information storage unit 5 that acquires position information P1 of the portable communication terminal 4, a blowing unit selection processing unit 6 that selects a specific blowing unit 2 provided in the vicinity of the portable communication terminal 4 based on the position information P1 acquired by the position information storage unit 5 and performs a process of combining and linking the blowing fan 3 of the selected blowing unit 2 with the portable communication terminal 4, and a fan control information processing unit 7 that controls the blowing fan 3 selected by the blowing unit selection processing unit 6 based on air conditioning instruction information P2 operated on the portable communication terminal 4.

[0017] 2, the blowing unit 2 includes a cylindrical housing 23 with a bottom that is fitted into a circular hole 21a formed in a floor panel 21. The housing 23 houses, from top to bottom, an airflow direction adjustment device 10, a shutter 8 (described later), and a blowing fan 3.

[0018] 1, each of the blowing units 2 is provided with a position detection unit 40 that detects a nearby mobile communication terminal 4. An example of the position detection unit 40 is a beacon.

[0019] As shown in Fig. 3, a plate-shaped cover member 24 that covers the opening at the top of the housing 23 is provided as an air outlet at the top end of the housing 23, fixed to the periphery of the circular hole 21a of the floor panel 21. The cover member 24 has a plurality of through holes 24a. The shape and size of the through holes 24a in the cover member 24 can be set as desired, for example. A rotation operation unit 13 of the airflow direction adjustment device 10, which will be described later, is disposed in the center of the cover member 24.

[0020] The blow-out fan 3 is provided with an airflow direction adjustment device 10 that changes the direction of the conditioned air E blown out from the blow-out section 2. The fan control information processing unit 7 drives the airflow direction adjustment device 10 based on air-conditioning instruction information P2 operated on the mobile communication terminal 4 to control the direction of the conditioned air E blown out from the blow-out section 2.

[0021] As shown in Figures 2 to 5, the air direction adjustment device 10 comprises a rotating shaft 11 extending in a direction perpendicular to the floor surface, a plurality of inclined blades 12 fixed to the rotating shaft 11 and arranged in a row in a direction perpendicular to the rotating shaft 11, and a rotation operating unit 13 fixed integrally to the upper end of the rotating shaft 11.

[0022] The multiple inclined blades 12 are fixed to the inside of a circumferential frame 14 centered on the rotation shaft 11. The circumferential frame 14 is provided integrally with the rotation shaft 11. By gripping and rotating the rotation operation part 13 arranged in the center of the cover member 24 with a hand, the circumferential frame 14 and the multiple inclined blades 12 rotate integrally around the rotation shaft 11.

[0023] The airflow direction control device 10 of this embodiment is disposed with the rotation axis 11 facing in a direction perpendicular to the floor surface. That is, the arrangement direction of the multiple inclined blades 12 is parallel to the floor surface. In the airflow direction adjustment device 10, the multiple inclined blades 12 are rotated to an appropriate rotation position by controlling the fan control information processing unit 7, thereby changing the airflow direction. Note that Fig. 5 shows a state in which the orientation of the inclined blades 12 is reversed (rotated 180°) from that in Fig. 2.

[0024] 2, a shutter 8 that opens and closes the air outlet is provided in the air outlet unit 2. The opening and closing operation of the shutter 8 is controlled by the fan control information processing unit 7 based on the air conditioning instruction information P2 of the mobile communication terminal 4. The shutter 8 has a fixed plate 81 fixed to the inner surface of the container 23 with its plate surface facing horizontally, a sliding plate 82 arranged to be slidable in one direction along the upper surface 81a of the fixed plate 81, and an extendable cylinder 83 arranged below the fixed plate 81 and sliding the fixed plate 81 in the one direction.

[0025] The fixed plate 81 has a plurality of first slits 81b extending in a first direction (a direction perpendicular to the paper surface in FIG. 2) arranged in a second direction (left-right direction on the paper surface in FIG. 2) perpendicular to the first direction in top view. The sliding plate 82 has a plurality of second slits 82b extending in the first direction arranged in a second direction perpendicular to the first direction in top view. The telescopic cylinder 83 is disposed so that the telescopic shaft 84 appears and disappears in the second direction. A connecting shaft 85 fixed to the lower surface 82a of the sliding plate 82 is provided at a tip 84a of the telescopic shaft 84. The sliding plate 82 reciprocates in the second direction as the telescopic shaft 84 extends and retracts.

[0026] The shutter 8 is configured to be able to selectively take an open position 8A shown in FIG. 3 and a closed position 8B (see FIG. 5). That is, when the shutter 8 is in the open position 8A as shown in FIG. 3, the first slit 81b and the second slit 82b communicate in the vertical direction, and the conditioned air E blown from the blower fan 3 flows from the lower part of the shutter 8 to the upper part. On the other hand, when the shutter 8 is in the closed position 8B as shown in FIG. 5, the first slit 81b is arranged shifted in the first direction with respect to the second slit 82b, that is, the opening of the first slit 81b can be blocked by the sliding plate 82 with an appropriate opening amount, and the flow passage of the conditioned air E from the lower part of the shutter 8 to the upper part is blocked. The telescopic action of the telescopic cylinder 83 is operated in response to an external control signal using a solenoid or the like.

[0027] As shown in FIG. 1, the mobile communication terminal 4 has a function of transmitting air conditioning instruction information P2 for operating a desired blower fan 3 by operation to the fan control information processing unit 7 via communication. The position information storage unit 5 is a processing unit that performs a process of acquiring and storing the position information P1 of the mobile communication terminal 4. In the position information storage unit 5, the blowing unit 2 and the position detection unit 40 are linked together. The blowing section selection processing unit 6 is a processing unit that, based on the location information P1 acquired by the location information storage unit 5, performs a process of combining and linking the mobile communication terminal 4 corresponding to the location information P1 with the blowing fan 3 of the blowing section 2 provided in the vicinity of the mobile communication terminal 4, to select a specific blowing fan 3.

[0028] The fan control information processing unit 7 receives air conditioning instruction information P2 operated on the mobile communication terminal 4, and performs processing to control the blowing fan 3 of the blowing unit 2 specified by the blowing unit selection processing unit 6 with the fan control unit 9 based on this air conditioning instruction information P2. The fan control unit 9 performs ON / OFF and air volume adjustment using an app installed on the mobile communication terminal 4, and selects a comfortable air volume according to the situation of the operator M. When the blowing fan 3 is started, the shutter 8 is set to the open position 8A at the same time as the operation, and the conditioned air E sent from the blowing fan 3 is supplied to the indoor side. When the blowing fan 3 is stopped, the shutter 8 is set to the closed position 8B, and the supply of the conditioned air E to the room is stopped.

[0029] The wiring to the fan control unit 9 in the blowing unit 2 has a power line and a communication line for control, and the PoE power supply method is adopted. This simplifies the wiring into a single system, and reduces the effort and time required for wiring connection processing during installation compared to the conventional case where the power line and communication line are wired separately.

[0030] Next, the air conditioning control method for supplying air-conditioning air E into the room from multiple air outlets 2 arranged at predetermined positions on the floor panel 21 using the above-mentioned air conditioning control system 1, and the function of the air direction adjustment device 10 will be described in detail with reference to the drawings.

[0031] First, as shown in Fig. 1, position information P1 of the mobile communication terminal 4 held by the operator M is acquired by the position information storage unit 5. Next, air conditioning instruction information P2 operated on the mobile communication terminal 4 is received by the fan control information processing unit 7. After that, the blowing unit selection processing unit 6 combines and links the mobile communication terminal 4 with the blowing fan 3 of a specific blowing unit 2 provided in the vicinity of this mobile communication terminal 4 based on the position information P1 acquired by the position information storage unit 5. Furthermore, the fan control information processing unit 7 transmits a control command to the fan control unit 9 corresponding to the selected blowing fan 3 so as to control the blowing fan 3 of the blowing unit 2 selected by the blowing unit selection processing unit 6 based on the received air conditioning instruction information P2.

[0032] In this embodiment, the position of a user (operator M) carrying a mobile communication terminal 4 can be identified, and an appropriate volume of conditioned air E can be blown out from the blowing section 2 provided in the vicinity of the position of the operator M. Furthermore, in this embodiment, the air conditioning can be adjusted to the optimum level according to the location of the operator M and the air conditioning instruction information P2 transmitted by the operator M by operating the mobile communication terminal 4, thereby improving the comfort of the operator M.

[0033] In addition, in this embodiment, in the airflow direction adjustment device 10, the airflow direction can be easily changed in a direction rotating around the up-down direction by rotating the rotating operation unit 13 to rotate the multiple inclined blades 12. In addition, since the rotating operation unit 13 and the multiple inclined blades 12 are supported by the same rotation shaft 11, this can be achieved with a simple structure.

[0034] In this embodiment, the wind direction can be adjusted as desired by the wind direction adjustment device 10. Therefore, even if the user's position is misaligned with respect to the blow-out section 2, the wind direction adjustment device 10 can change the direction of the blown airflow, so that the conditioned air E can be provided in the optimal direction toward the user (operator M), thereby improving the comfort of the operator M. Therefore, in this embodiment, the direction of the conditioning air E blown out from the floor-blowing type blowing section 2 can be easily adjusted.

[0035] In addition, in this embodiment, the multiple inclined blades 12 are fixed to the inside of a circumferential frame 14 centered on the rotation axis 11, the circumferential frame 14 is formed integrally with the rotation axis 11, and by rotating the rotating operating part 13, the circumferential frame 14 and the multiple inclined blades 12 rotate integrally, so that the structure is simple and can be easily incorporated into building structures such as the floor slab 21 as in this embodiment.

[0036] As described above, in the underfloor airflow direction adjustment device according to this embodiment, the direction of the air for conditioning E blown out from the underfloor airflow outlet section 2 can be easily adjusted.

[0037] The above describes an embodiment of the airflow direction adjustment device for floor airflow according to the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the present invention.

[0038] For example, in this embodiment, the air direction adjustment device 10 is configured such that multiple inclined blades 12 are fixed inside a circumferential frame 14 centered on the rotating shaft 11, but the configuration is not limited to having a circumferential frame 14, and it is also possible to omit the circumferential frame 14. Furthermore, the shape of the airflow direction adjustment device 10 is not limited to being circular when viewed from the direction of the rotation shaft 11, and may be rectangular. In short, it is sufficient that the device is rotatable around the rotation shaft 11 and has a plurality of inclined blades 12 arranged in the horizontal direction.

[0039] In addition, in this embodiment, the air direction adjustment device 10 is shown as an example provided as part of the air conditioning control system 1, but it is not limited to being used as such a control system, and it is of course possible to use the air direction adjustment device 10 as a standalone device. For this reason, in this embodiment, the fan control information processing unit 7 is configured to control the airflow direction adjustment device 10 to adjust the airflow direction based on the air conditioning instruction information P2 operated on the mobile communication terminal 4, but the present invention is not limited to this. In other words, the airflow direction adjustment device 10 may be separated from the fan control information processing unit 7, and the inclined blades 12 of the airflow direction adjustment device 10 may be manually rotated by the rotation operation unit 13 to adjust the airflow direction.

[0040] Also, the blower unit 2 is provided with a shutter 8 that opens and closes the blower outlet, and the opening and closing operation of the shutter 8 is controlled by the fan control information processor 7 based on the air conditioning instruction information P2 of the mobile communication terminal 4, but the invention is not limited to this configuration. Also, the shutter 8 may be omitted.

[0041] In addition, in this embodiment, the configuration is such that a position detection unit 40 is provided for detecting a mobile communication terminal 4 located near the blowing unit 2, but as described above, it is possible to adopt another position detection unit instead of the position detection unit 40 such as a beacon, or it is also possible to omit the position detection unit 40. For example, as the other position detection unit 40, it is possible to adopt a Wi-Fi access point capable of detecting the mobile communication terminal 4, a camera capable of image processing of the mobile communication terminal 4 from captured images, an image recognition type human presence sensor, or the like.

[0042] In addition, the components in the above-described embodiments can be replaced with well-known components as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
