Description

  The present invention relates to a vacuum cleaner.

  In conventional vacuum cleaners, either the canister type in which the suction port and the vacuum cleaner main body move separately or the upright type in which the suction port and the vacuum cleaner main body move together can be selected. In any use form, a vacuum cleaner that can be easily moved and operated has been proposed (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2003-265281

  Some conventional vacuum cleaners include a transparent dust collecting part in a suction conduit near the hand. Since this type of vacuum cleaner can be cleaned while checking the amount of dust accumulated in the dust collection section through the transparent container of the dust collection section, there is an advantage that the user can obtain a sense of accomplishment of cleaning.

  However, a vacuum cleaner of the type that can select a canister type or an upright type of usage like the vacuum cleaner of Patent Document 1 is provided with a dust collecting part on the main body side of the vacuum cleaner. It is not possible to check the amount of dust that has accumulated in the dust collection section.

  The present invention has been made in view of such a problem, and the configuration in which the dust collecting unit is provided in the suction conduit near the hand so that the user can clean the dust while checking the amount of dust accumulated in the dust collecting unit. An object of the present invention is to provide a vacuum cleaner that can select different types of usage.

  Thus, according to the present invention, there is provided a vacuum cleaner comprising a first cleaning unit and a second cleaning unit, wherein the first cleaning unit is configured from a first air inlet and air sucked from the first air inlet. A dust collecting unit for separating and collecting dust; and a first exhaust port for discharging the air from which the dust is separated. The second cleaning unit draws air from the second air inlet and the second air inlet. An electric blower that sucks, a power supply unit that drives the electric blower, and a second exhaust port that discharges air sucked into the electric blower, wherein the first exhaust port and the second intake port are directly or A vacuum cleaner is provided that is detachably connected via a flexible hose.

  According to the vacuum cleaner of the present invention, it is possible to realize a vacuum cleaner capable of selecting different types of use forms while the suction conduit near the hand is provided with the dust collecting portion.

It is a left view of the 1st cleaning unit of the electric vacuum cleaner of Embodiment 1. It is a left view of the 2nd cleaning unit of the vacuum cleaner of Embodiment 1. It is explanatory drawing which shows the structure of the vacuum cleaner of Embodiment 1. FIG. It is explanatory drawing which shows the structure of the vacuum cleaner of Embodiment 2. It is a left view of the 2nd cleaning unit of the electric vacuum cleaner of Embodiment 3. It is explanatory drawing which shows the structure of the vacuum cleaner of Embodiment 4. It is explanatory drawing which shows the structure of the vacuum cleaner of Embodiment 5.

  The vacuum cleaner of the present invention is a vacuum cleaner composed of a first cleaning unit and a second cleaning unit, wherein the first cleaning unit is configured by using a first air inlet and air sucked from the first air inlet. A dust collecting unit for separating and collecting dust; and a first exhaust port for discharging the air from which the dust is separated. The second cleaning unit draws air from the second air inlet and the second air inlet. An electric blower that sucks, a power supply unit that drives the electric blower, and a second exhaust port that discharges air sucked into the electric blower, wherein the first exhaust port and the second intake port are directly or It is detachably connected via a flexible hose.

  “The first exhaust port and the second intake port are detachably connected directly or via a flexible hose” means, for example, that the connection portion of the first exhaust port and the second intake port is respectively When formed to be a male (or female) part and a female (or male) part, the connecting part of the hose connects the part connected to the first exhaust port to the female (or male) part and the second intake port. The part is formed to be a male (or female) part.

  The “power supply unit” may be either a battery or a power supply device that supplies power supplied from an external commercial power supply to each part of the vacuum cleaner via a power cord.

  Moreover, the vacuum cleaner of this invention may be comprised as follows, and may be combined suitably.

(1) The second cleaning unit includes a second handle, and the second handle functions as a portable device for carrying the entire vacuum cleaner in the first form in which the first exhaust port and the second intake port are directly connected. And in the 2nd form which connected the said 1st exhaust port and the said 2nd inlet port via the said flexible hose, it may function as an object for carrying the said 2nd cleaning unit.
In this way, the user can use the vacuum cleaner by switching between the first form and the second form while holding the second handle.
