  1 to 4, the air injection device 1 according to the present embodiment includes an opening 2, a discharge port 4, a suction chamber 6 equipped with a suction fan 5 inside, and a suction chamber for rotating the suction fan 5. 6, a suction port 7 for sucking outside air, a second suction port 8, an injection chamber 10 equipped with an injection fan 9 therein, a connecting portion 11 rotatably connected to the injection chamber 10, A rotary shaft 13 is provided as a power transmission means that holds the suction fan 5 and the injection fan 9 at both ends while being rotatably held by a bearing 12 fixed to the connecting portion 11.

  The suction fan 5 and the ejection fan 9 are formed of a sirocco fan, the discharge port 4 is at the rotation center of the suction fan 5 on the suction chamber 6, and the second suction port 8 is on the ejection chamber 10. In the center of rotation of the injection fan 9, an opening is provided on the surface opposite to the connecting portion 11.

  In addition, there is a switch 14 for switching communication between the opening 2 and the suction chamber 6 or the injection chamber 10, and a drive unit 15 and a control unit 16 for operating the switch 14 are provided in the vicinity of the switch 14. Is provided. Furthermore, it is composed of an acceleration sensor, a gyro sensor, and the like, and is a selection for switching between the operation detection means 17 for detecting an operation when the user moves the air ejection device 1 and whether the operation detection means 17 is to function or not. Means 18 and storage means 19 for storing the motion detected by the motion detection means 17 are provided.

  The operation of the air injection device 1 in the present embodiment configured as described above will be described.

  As shown in FIG. 2, when the switch 14 is moved to the injection chamber 10 side by the driving means 15, a connection pipe (not shown) or an extension pipe (not shown) connected to the vacuum cleaner body of the vacuum cleaner. When the discharge port 4 is connected to the discharge port 4 and the electric vacuum cleaner is operated in this state, a strong suction wind is generated from the discharge port 4.

  At that time, outside air is sucked from the opening 2 and the suction port 7, and intake air flows from the opening 2 to the discharge port 4 and from the suction port 7 to the discharge port 4 as shown by arrows in FIG. 2. . The suction port 7 is covered with a mesh-like shape that prevents the dust from being sucked so that the surface of the suction port 7 is not fully opened so that only the outside air is sucked without sucking dust. In addition, when the user brings the opening 2 close to the floor surface or the like to be cleaned, if there is dust on the floor surface, the user sucks the dust from the opening 2 and passes through the connection pipe from the discharge port 4 to the inside of the vacuum cleaner. Stored in the dust collection chamber.

  Next, as shown in FIG. 3, when the switch 14 is moved to the suction chamber 6 side by the driving means 15, the air flow is blocked by the switch 14 from the opening 2, so that the opening 2 This suction air does not flow, and a suction air amount is generated from the suction port 7 toward the discharge port 4 as shown in the figure. At this time, the suction fan 5 can be rotated by the suction air sucked from the suction port 7. The power of the rotating suction fan 5 is transmitted to the injection fan 9 through the rotating shaft 13 rotatably held by the bearing 12 to rotate the injection fan 9. The rotated ejection fan 9 sucks outside air from the second suction port 8 and ejects air sucked from the opening 2. In FIG. 3, the flow of the suction air and the erupting air at that time is indicated by arrows.

  In this way, by switching the switch 14, it becomes possible to perform suction from the opening 2 or to blow out air, so that the opening 2 is brought close to the floor surface or the like to be cleaned, and the dust on the floor surface It becomes possible to perform the cleaning by sucking the water or jetting it in reverse.

  Here, as a means for switching the switching device 14, an example of a method for detecting the operation by the operation detecting means 17 and switching the switching device 14 will be described.

  When the user operates the air injection device 1, information such as the direction, the number of times, and the strength of the operation performed by the acceleration sensor and the gyro sensor constituting the operation detection unit 17 can be obtained.

  When the same operation as the preset operation condition is performed, it is determined that the user has intentionally performed the operation, and the driving unit 15 is driven to switch the switch 14. As an example, as shown in FIG. 4 (A), when the air injection device 1 is shaken a plurality of times in the vertical direction, the air flow from the opening 2 is ejected. When the air jet device 1 is shaken a plurality of times in the left-right direction as described above, if the air flow from the opening 2 is set to be sucked, the user can switch the lever without switching the lever or the like. It is easy and quick to switch between ejection and suction.

  Next, the selection means 18 enables the operation detection means 17 to detect the user's action and to select whether or not to switch the switch 14. As an example, when the selection unit 18 does not detect the user's motion in the motion detection unit 17, the selection unit 18 is fixed so as to eject the air flow from the opening 2. Thereby, it becomes possible to prevent the ejection and suction from being switched in a situation not intended by the user.

  Next, the user can freely set the operation of switching between suction and ejection by the storage means 19. For example, a storage element (not shown) and a switch (not shown) for storing the operation in the storage means 19 are provided, and the user performs a desired operation while pressing the switch, and thereafter The operation is stored in the storage element when the finger is released from the switch.

  As a result, the switch 14 can be switched by an operation that is easy for the user to perform. In addition, when the detection means 17 does not perform detection by the selection means 18, whether the air flow from the opening 2 is ejected or suctioned is stored in the storage means 19. Furthermore, it becomes possible to provide the air ejecting apparatus 1 capable of performing an operation suitable for the user's convenience.

When the user is cleaning, since the air injection device 1 is always moving, the motion detection means 17 detects a random motion. When the user interrupts the cleaning, for example, when the air injection device 1 is placed somewhere, the motion detection means 17 will not detect the motion.

  Therefore, when there is no operation detected by the operation detection unit 17 for a predetermined time, it is determined that the user has stopped cleaning, and the operation detection unit 17 communicates with the communication unit 20 and the connection pipe 52 or extension pipe. A signal is transmitted to the main body control means 49 in the cleaner main body 50 via the communication line 55, and the operation of the electric blower 57 in the cleaner main body 50 is stopped by the main body control means 49.

  Next, when the operation is detected again by the operation detection means 17 in the air injection device 1 when the electric blower 57 is stopped, it is determined that the user has resumed cleaning, and the cleaner The signal of the operation detection means 17 is transmitted to the main body control means 49 through the communication means 20 so that the electric blower 57 in the main body 50 is operated again.

  As described above, according to the present embodiment, since it is not necessary for the user to perform an operation such as a lever operation, even a weak person such as an elderly person can easily and easily understand the ejection function and the suction function. It is possible to provide an air jet device that can be switched and that has an energy saving effect by suppressing wasteful power, and that is very easy to use.

  In addition, by using the air injection device 1 described in the above embodiment for a vacuum cleaner, it is possible to switch between the functions of injection and suction with a simple operation, thus providing a very convenient vacuum cleaner. be able to.

  As described above, the air injection device according to the present invention and the vacuum cleaner using the same suck air from the opening, and perform sufficient suction when there is dust and want to suck, and at the same time air from the opening. It can be easily and efficiently cleaned in places that are difficult to clean with normal suction, and it can be switched with a simple operation, and it can be cleaned very easily.
