  However, in the configuration of the conventional vacuum cleaner suction tool, as shown in FIG. 12, for example, the extension pipe 41 is connected to the second suction tool 40 removed from the first suction tool (not shown), When cleaning the ceiling or the grill of an air conditioner provided on the ceiling, the connection pipe 42 of the second suction tool 40 can be turned to the left and right only with the second suction port 43 facing downward. Since the second suction port 43 cannot be reversed, i.e., cannot be turned directly upward, the handle 46 provided at the end of the hose 44 and connected to the extension pipe 41 must be turned upside down. There was a problem that it was extremely unusable.

  In order to solve this problem, it is conceivable that the connecting pipe 42 can be simply rotated 360 degrees. However, in this case, the second suction tool 40 is attached to the first suction tool to perform normal floor cleaning. When the extension pipe 41 is lifted up, the first suction tool is easily reversed or in the vertical direction, which is very unusable.

  In addition, the one disclosed in Patent Document 2 needs to increase the vertical rotation range of the connection pipe, but depending on the configuration of the connection pipe, the rotation range cannot be increased, and this configuration may not be used. It was.

  The present invention solves the above-described conventional problems. When cleaning a normal floor surface by mounting the second suction tool on the first suction tool, the electric vacuum cleaner is held with an extension pipe during the cleaning operation. When the vacuum cleaner is lifted, the vacuum cleaner vacuum will not be reversed, and the second vacuum cleaner is removed from the primary vacuum cleaner and the ceiling or the grill of the air conditioner installed on the ceiling When cleaning, etc., it can be easily operated without changing the orientation of the extension tube. Or, even when using a connecting pipe whose vertical rotation is restricted, it is possible to easily clean the upper surface of a high place such as an air conditioner. It aims at providing the suction tool for vacuum cleaners which can easily clean a high place using a 2nd suction tool, and a vacuum cleaner using the same.

  In order to solve the above-described conventional problems, the vacuum cleaner suction tool of the present invention is provided on the bottom surface with the first suction tool that sucks dust on the surface to be cleaned from the first air inlet provided on the bottom surface. A second suction tool that sucks dust from the second suction port and is detachably attached to the first suction tool from above; an extension communicating with the main body of the vacuum cleaner behind the second suction tool. When the pipe is connected and has a connecting pipe that is rotatable in the vertical and horizontal directions, and the second suction tool is attached to the first suction tool, the connecting pipe is rotated in the horizontal direction. The movement range is restricted, and when the second suction tool is separated from the first suction tool, the second suction port can be rotated at least until it is in an upward state. When cleaning the floor with the suction tool attached to the first suction tool, the extension pipe is connected. Since the range of rotation of the connecting pipe in the left and right direction is restricted, when the vacuum cleaner suction tool is lifted by holding the extension pipe during cleaning work, the vacuum cleaner suction tool may be reversed. No. When removing the second suction tool from the first suction tool and cleaning the ceiling or the grill of the air conditioner installed on the ceiling, the second suction port of the second suction tool can be turned upward. Since it can rotate, the operation of the extension tube is easy and it is very convenient to use. Alternatively, in the case of using a connecting pipe that is restricted from turning in the vertical direction, the upper surface of an air conditioner or the like can be easily cleaned by rotating in the left-right direction until the intake port of the second suction tool faces upward. I can do it.

  Moreover, the vacuum cleaner of this invention is the vacuum cleaner main body which incorporated the electric blower, the suction tool for vacuum cleaners of any one of Claims 1-4, the said vacuum cleaner main body, and an electric cleaner. It is equipped with a hose that communicates with the machine suction tool, and can provide an easy-to-use vacuum cleaner.

  The vacuum cleaner suction tool and vacuum cleaner according to the present invention are the second suction tool removed from the first suction tool as well as the usual floor surface cleaning performed by attaching the second suction tool to the first suction tool. The ceiling and the grill of the air conditioner installed on the ceiling can be easily cleaned, making it easy to use.

  According to a first aspect of the present invention, there is provided a first suction tool for sucking dust on a surface to be cleaned from a first air inlet provided on a bottom surface, and a first suction tool for sucking dust from a second air inlet provided on a bottom surface. A second suction tool that is detachably attached to one suction tool, and an extension pipe communicating with the main body of the vacuum cleaner is connected to the rear of the second suction tool and is rotatable in the vertical and horizontal directions. When the second suction tool is attached to the first suction tool, the pivot range of the connection pipe in the left-right direction is restricted, and the second suction tool is the first suction tool. When separated from the suction tool, the second floor can be rotated at least until the second suction port is in an upward state, and the ordinary floor is mounted by attaching the second suction tool to the first suction tool. When cleaning the surface, the rotation range in the left-right direction of the connecting pipe to which the extension pipe is connected is restricted. In, during cleaning work, when you lift the vacuum cleaner suction device with an extension tube, it is not to be inverted for an electric vacuum cleaner suction tool. When removing the second suction tool from the first suction tool and cleaning the ceiling or the grill of the air conditioner installed on the ceiling, the second suction port of the second suction tool can be turned upward. Since it can rotate, the operation of the extension tube is easy and it is very convenient to use.

  In the second invention, in particular, the second suction tool of the first invention is provided with locking means for locking the rotation in the left-right direction with the second air inlet facing upward. When cleaning the ceiling or the grill of an air conditioner installed on the ceiling with the removed second suction tool, the main body portion of the second suction tool does not sway and is very convenient to use.

  In the third invention, in particular, when the second suction port of the second suction tool of the first invention is in an upward state, the vertical rotation range of the connection pipe is restricted, and the connection pipe is necessary. Since the rotation is restricted as described above, the operation of the vacuum cleaner suction tool becomes easy.

  According to the fourth aspect of the invention, in particular, the main body of the second suction tool of the third aspect of the invention and the protruding part protruding from both of the connection pipes are fitted to restrict the vertical rotation range of the connection pipe. Thus, the rotation range can be regulated with an inexpensive configuration.
