JP 2003-61878 A

  According to the configuration of the electric vacuum cleaner described above, when the electric vacuum cleaner is transported, it is transported using the handle 65, but since the hose 66 is disposed on the handle 65, the electric vacuum cleaner There is a problem of increasing the size. Further, when the handle 65 is gripped, it is necessary to grip the hose 66 at the same time, and there is one aspect of poor usability. Further, the hose 66 is provided with a connecting pipe 67 detachably at one end, and when the hose is removed from the connecting port 70, the hose 66 disposed on the handle 65 is also detached from the handle 65. In this case, since the thickness of the handle 65 is reduced, there is a problem that the handle 65 is difficult to grasp. Accordingly, the present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an electric vacuum cleaner capable of reducing the size of the electric vacuum cleaner and improving operability.

  In the electric vacuum cleaner based on this invention, the vacuum cleaner main body which incorporates an electric blower, the dust collection chamber provided in the front part of the said vacuum cleaner main body, and the downward arrangement | positioning of the said vacuum cleaner main body, and attracting | sucking dust A suction port, an operation handle disposed behind the dust collection chamber and above the vacuum cleaner body, and disposed on one side surface of the vacuum cleaner body, one of which is the suction port A first air intake passage that communicates with the body and the other communicates with the dust collecting chamber and a second side surface of the cleaner body, and one communicates with the dust collecting chamber and the other communicates with the electric blower. The dust sucked from the suction port body is sent to the dust collection chamber after being guided to the first suction passage, and the air in which the dust is filtered by the dust collection chamber is the second suction channel. 2 It is sent to the electric blower by the intake passage and exhausted to the outside of the cleaner body. Is characterized in that air flow is formed that.

  According to the vacuum cleaner based on this invention, the dust attracted | sucked from the suction inlet body is guide | induced to a 1st air intake passage, and is sent into a dust collection chamber through a 1st air intake passage. The air filtered by the dust collecting chamber is sent to the electric blower through the second air intake passage and exhausted to the outside of the cleaner body. In this way, a series of air flows from the suction port body to the electric blower through the dust collection chamber is formed using the first intake passage and the second intake passage provided on the side surface of the cleaner body. This eliminates the need for an air intake passage that surrounds the handle body, and allows the vacuum cleaner body to be miniaturized. Further, since it is not necessary to form an intake passage using the handle body, the shape of the handle body can be designed to be easy to hold, and the operability of the vacuum cleaner can be improved.

  Hereinafter, the structure of the vacuum cleaner in each embodiment based on this invention is demonstrated, referring a figure. In each embodiment, the same or corresponding parts are denoted by the same reference numerals, and redundant description will not be repeated.
