The cover member 62 is in the form of a mesh having air permeability, and the outer periphery of the cover member 62 is attached to the guard member 60, and the central portion of the cover member 62 is in the form of a dome which bulges downward. The cover member 62 covers the main body 32 and the rotary wings 34 from the lower side.

  In the present embodiment, the blowing system of the present invention is configured by the blowing flying object 30, the temperature sensor 16, and the control unit 18. In the present embodiment, the control unit 18 is provided inside the air-blowing flying object 30, but the control unit 18 is provided separately from the air-blowing flying object 30, and various instructions are transmitted to the air-flying flying object 30. , And the air-flying vehicle 30 may be controlled.

  A temperature sensor 68 is disposed at a central portion of the skeleton 32C. The temperature sensor 68 is capable of measuring the temperature, measures the temperature of the portion where the air-flying flying object 30 is disposed, and transmits the measured temperature data to the control unit 18.

  Next, the operation of the blowing flying object 30 in the present embodiment will be described.

  When not in use, as shown in FIG. 7, the air-flying vehicle 30 is stored in the storage unit 22 of the air conditioner 20. In the storage unit 22, a part of the blowing flying object 30 in the horizontal direction is disposed inside the air conditioner 20 from the opening 24, and the other half protrudes outward.

  In use, the user turns on a switch (not shown) to operate the air-flying vehicle 30. The operation of the air-flying vehicle 30 may be during the operation of the air conditioner 20 or may be during the non-operation of the air conditioner 20. In addition, the air-handling vehicle 30 does not have to be operated at the time of use of the air conditioner 20, and can be operated as required.

  When the air-blowing flying object 30 is in operation, the rotary wings 34 are rotated to move the air-blowing flying object 30 to the ceiling 12, and the rotating portion 49 of the leg 40 is pressed against the ceiling 12. Then, it moves to the place instructed by the control unit 18.

  In the control unit 18, the moving destination of the airborne flying object 30 is based on temperature information from the plurality of temperature sensors 16 installed on the ceiling 12 and the wall surface 14 and the temperature sensor 68 provided on the airborne flying object 30. Decide. For example, the location where the temperature is the highest during the cooling operation of the air conditioner 20 is the destination, and the location where the temperature is the lowest during the heating operation is the destination. In the present embodiment, as an example, as shown in FIG. 8, a high temperature position ventilation feedback process is performed. In the high temperature position air flow feedback processing, data of temperatures detected by the temperature sensors 16 and 68 are acquired in step S10. Next, in step S12, the positions of the temperature sensors 16 and 68 that have detected the temperature data of the highest temperature among the acquired temperature data are transmitted to the air vehicle 30 as the movement destination data. Then, in step S14, the process waits until a predetermined time has elapsed, and after the predetermined time has elapsed, the process returns to step S10 and the above-described process is repeated. This high temperature position air flow feedback processing is continued until the operation of the airborne vehicle 30 is completed.

  The airborne flying object 30 having received the movement destination data rotates the rotor 34 to generate lift, and obtains the propulsive force by tilting the rotation shaft 34A of the rotor 34 with respect to the vertical direction, and moves Go ahead. When the airborne flying object 30 moves, the airborne airborne object 30 is controlled such that the number of rotations on the front side in the moving direction is reduced by controlling the rotational speed of each of the rotary wings 34 to lower the moving direction front side. Is inclined, and rotation is continued in a state in which the rotation shaft 34A is inclined to provide a propelling force toward the movement destination. At the time of movement, the rotating portion 49 is pressed against the ceiling 12, and the leg portion 40 is expanded and contracted by the biasing force of the inner spring 46 A and the outer spring 44 B according to the inclination of the blowing flying object 30. The state is maintained (see FIG. 4).

  At this time, as shown in FIG. 9, when there is an obstacle N1 on the front side in the moving direction, the horizontal position sensor 66 detects the presence of the obstacle N1 and moves avoiding the obstacle. Further, as shown in FIG. 10, when the vertical position sensor 64 detects a recess, a protrusion, or another obstacle N2 on the ceiling 12, the obstacle N2 is moved while avoiding the detected obstacle N2. After arriving at the moving destination, as shown in FIG. 11, the rotary shaft 34A is returned in the vertical direction, and the leg 40 is hovered while being pressed against the ceiling 12. At this time, the legs 40 of the air-flying vehicle 30 are disposed in the vertical direction, and the rotary wings 34 are maintained in the vertically downward state. In this state, the air is sent to the lower side of the air-flying vehicle 30 by the rotation of the rotary wings 34, and the air is agitated. As a result, it is possible to lower the temperature of the moving destination which has been partially high.

  In the above description, the place where the temperature is the highest is the move destination, but when heating, the place where the temperature is the lowest may be the move destination, or the move destination may be determined by an instruction from the user.

  When stopping the operation of the air-flying vehicle 30, the air-flying air vehicle 30 is moved to the vicinity of the air conditioner 20 while the leg portion 40 is in contact with the ceiling 12. Then, the air-flying vehicle 30 is landed on the base portion 26, and the rotary wings 34 are stopped.

  Next, an emergency process when the blowing aircraft 30 breaks down during use will be described.

  When an airborne abnormality occurs after the air-blowing air vehicle 30 has been activated, the airborne abnormality signal is transmitted from the control unit 18. The winding device 52 receives the flight abnormality signal and the motor 52B is activated, and the reel 52A is rotated to wind the power cable 50 by the reel 52A. As a result, as shown in FIG. 6, the blowing flying object 30 is suspended without falling.

  The air-flying vehicle 30 of the present embodiment can be moved along the ceiling 12 of the room by the lift and propulsive force of the rotary wings 34, and thus no special equipment is provided on the ceiling. Therefore, it is possible to move and blow air to a place simply required indoors. Thereby, the temperature unevenness in the room can be effectively eliminated. Further, as in the case of providing a facility on the ceiling, maintenance of the facility is not necessary.

  Further, in the air-blowing flying object 30 of the present embodiment, since the propulsive force is obtained by controlling the rotational speed of the rotary wing 34 and tilting the rotation shaft 34A, a separate member for obtaining the propulsive force is provided. There is no need for it, and a simple configuration can be made.

  Moreover, since the air-flying vehicle 30 according to the present embodiment includes the legs 40, when hovering near the ceiling 12, the hovering state can be maintained in a state where the legs 40 are pressed against the ceiling 12. . In the vicinity of the ceiling, it is difficult to maintain the flight attitude by the air flow generated by the rotation of the rotary wings 34 in the vicinity of the ceiling, but the flight attitude can be easily stabilized by pressing the legs 40 against the ceiling 12 be able to. Further, when moving along the ceiling 12, the rotational speed of the rotary wings 34 is controlled to tilt the air-flying flying object 30 (rotational shaft 34 A) while pressing the rotating portion 49 against the ceiling 12. At this time, the plurality of legs 40 are expanded and contracted by the biasing force of the inner spring 46A and the outer spring 44B, and the contact state with the ceiling 12 is maintained, so that the airman 30 can be moved stably. . Moreover, since the rotation part 49 of the leg part 40 rolls at the time of movement, it can be made to move smoothly.

  Further, since the vertical position sensor 64 is provided on the radially outer side of the portion where the leg portion 40 of the frame portion 32C is attached, the flying object 30 for air blowing of the present embodiment The vertical position sensor 64 can detect an obstacle or a dent. Thereby, the airborne vehicle 30 can avoid obstacles and dents.

  Further, since the horizontal position sensor 66 is provided on the outer periphery of the guard member 60 at a position corresponding to the frame portion 32C, the blowing flying object 30 has an obstacle on the front side in the traveling direction at the height of the guard member 60. Can be detected. Thereby, the airborne vehicle 30 can avoid an obstacle.

  Moreover, the flying member 30 for blowing of this embodiment is provided with a guard member 60 on the radial direction outer side of the main body 32 and the rotary wings 34. Therefore, in the case where detection of an obstacle by the horizontal position sensor 66 is delayed or an obstacle jumps in, etc., the obstacle can be prevented from colliding with the rotary wing 34, and the rotary wing 34 can be protected. .

  In addition, when the flying object 30 according to the present embodiment causes a flight abnormality and a risk of falling occurs, the power cable 50 is wound around and suspended by the reel 52A. Thereby, the falling of the airborne vehicle 30 can be prevented, and the safety can be enhanced.

  Further, since the air-blowing flying object 30 of the present embodiment flies by itself, it can be controlled to move to the floor at the time of maintenance and the like, and there is no need to access high places and perform maintenance and the like. Therefore, maintenance can be easily performed.
